 "We're still here. We're still fighting. We still believe, as this race really shows," Santorum told supporters in Green Bay, Wis. 
  
 Although the victory gives Santorum bragging rights and at least nine more delegates, it does not change the overall dynamics of the race; the former Pennsylvania senator still dramatically lags behind Romney in the hunt for delegates to the GOP's summertime nominating convention. 
  
 Even so, Santorum's win underscores a pattern in the drawn-out race. 
  
 The under-funded underdog has tended to win in Bible Belt states that include Tennessee, Mississippi and Alabama. Romney _ a deep-pocketed, highly organized former Massachusetts governor _ has persistently struggled in such heavily conservative regions. 
  
 Said Santorum: "I'm not running as a conservative candidate for president. I am the conservative candidate for president." 
  
 Neither candidate was in the state as Louisiana Republicans weighed in. Nor was former House Speaker Newt Gingrich, who was trailing in Louisiana. With half the precincts counted, Santorum had 49 percent to 26 percent for Romney. Gingrich was far back at 17 percent, followed by Ron Paul with 6 percent. 
  
 Romney tweeted his congratulations to Santorum: "Congratulations to Rick Santorum in LA. I look forward to the contests to come and to defeating (at)BarackObama in November." 
  
 Romney took a rare day off Saturday, with no public events. Santorum spent the day campaigning in Pennsylvania and next-up Wisconsin, which votes April 3 and represents one of his last chances to beat Romney in a Midwestern state. 
  
 Santorum told voters in Milwaukee that he expected their state to be "the turning point in this race." 
  
 In an unmistakable jab at Romney, Santorum added: "Don't make the mistake that Republicans made in 1976. Don't nominate the moderate. When you do, we lose." It was a reference to Ronald Reagan losing the 1976 Republican nomination to incumbent President Gerald Ford, and Democrat Jimmy Carter winning the White House. 
  
 Exit polls conducted for The Associated Press and the television networks showed that Santorum's win in Louisiana was one of his strongest performances to date among conservatives, working class voters and those calling the economy their top issue. And he continued his dominance among white evangelical voters and those looking for a candidate who shares their religious beliefs. Santorum topped Romney among evangelical voters by more than 2 to 1. 
  
 As in previous Southern states, Romney's best showing came among those voters with annual incomes above $100,000 and those who prioritized a candidate's ability to defeat President Barack Obama in November. 
  
 The bad economy was the top issue for Louisiana voters. Most were gloomy about prospects for a recovery, saying they felt the economy was getting worse instead of better. While some national surveys suggest Americans are feeling optimistic about economic improvement, just one in eight Republican primary voters said they thought a recovery was under way. 
  
 Romney is far ahead in the delegate count and on pace to reach the necessary 1,144 delegates before the party's convention in August. 
  
 With the Louisiana results, Romney leads the overall race for delegates with 563, followed by Santorum with 272, Newt Gingrich with 135 and Ron Paul with 50. 
  
 Santorum badly needed a rebound after a decisive Illinois loss to Romney earlier in the week that moved party stalwarts to rally around the front-runner. Many urged Santorum and Gingrich to drop out of the race. 
  
 Both refused, and campaigned aggressively in Louisiana in hopes that a victory there would justify them staying in _ despite Republican worries that the long nomination fight could hurt the party's chances against Obama. The Democratic incumbent faces no serious primary challenge and his re-election campaign already is well under way. 
  
 Romney barely campaigned in Louisiana, though his allies spent on TV ads there. Instead, Romney was looking past the results and toward the general election. 
  
 "I want the vote of the people of Louisiana so we can consolidate our lead," Romney said Friday during a stop in Shreveport. He told supporters his campaign wants to focus on "raising the money and building the team to defeat someone that needs to be out of office in 2012, and that's Barack Obama." 
  
 Earlier Saturday, Santorum said he wanted to debate Romney without their trailing competitors on stage. 
  
 "This race has clearly gotten down to two candidates that can win the nomination," Santorum told reporters in Milwaukee. "I'd love to have a one-on-one debate." 
  
 In the run-up to Louisiana's voting, Santorum found himself on the defensive after suggesting he'd prefer a second term for Obama over a Romney presidency. Santorum was all but forced to walk back those comments, saying less than 24 hours before Louisiana polls opened that "over my dead body would I vote for Barack Obama." 
  
 Romney also faced trouble last week when a top aide compared the switch from a primary to a general election campaign to an Etch A Sketch toy, suggesting earlier campaign positions could be easily wiped away. 
  
 But most Louisiana voters said they weren't concerned with the comment, with only about one in five in exit polls calling this week's Etch A Sketch controversy an important factor in their vote. 
  
 Louisiana has complicated delegate rules: Even though there were 20 delegates at stake Saturday, they are awarded proportionally to the candidates who receive more than 25 percent of the vote. 
  
 Most states divide all the available delegates among the candidates who meet the minimum threshold. Louisiana's system is strictly proportional, with any leftover delegates designated as uncommitted, meaning they will be fought for at the state convention. 
  
 The next key fight comes April 3 in Wisconsin. Romney's campaign is airing TV ads in the state, and his super PAC allies have plowed more than $2 million into TV advertising there. 
  
 Also voting April 3 are Maryland and the District of Columbia. There are 95 delegates combined at stake in the three contests.

 Elliott reported from Milwaukee. Associated Press writer Marc Levy in Camp Hill, Pa., contributed to this report. ||||| NEW ORLEANS — Rick Santorum picked up another win on Saturday in Louisiana, but the victory won’t significantly change the delegate advantage held by Mitt Romney in the GOP nominating contest. 
  
 Santorum fell just short of winning 50 percent of the vote with 98 percent of precincts reporting, beating Romney by more than 22 percentage points. Romney nabbed 27 percent of the vote.

 Newt Gingrich finished third with about 16 percent, meaning he won’t win any delegates because of a 25- point threshold requirement for claiming them. 
  
 Santorum picked up only 10 delegates from the victory, with five going to Romney and five remaining unbound after Saturday’s vote. The Louisiana GOP will divide up the remaining 23 delegates through a caucus process in late April. 
  
 With the results pretty much set before voting began, the field of GOP hopefuls had already shifted its attention to future contests. Santorum and Gingrich spent Saturday in Pennsylvania, and Santorum went on to Wisconsin. Romney took a break from the trail this weekend and will resume campaigning Monday in southern California. 
  
 “I just want to thank you for making a very clear and crisp statement,” Santorum said in a celebration with a small group of reporters from a Wisconsin restaurant. “You don’t believe this race is over. You didn’t get the memo.” 
  
 Santorum signaled that he believed Wisconsin — which holds its primary on April 3 — would be a tipping point in the primary. He said that Romney had called to congratulate him from California, where the ex-Massachusetts governor is fundraising. Santorum told Romney that he should spare some of it for him. 
  
 “We’re here to fight,” Santorum pledged. “This race is long and far from over. And the people of Wisconsin, I say to you, ‘On Wisconsin. Let’s get it done.’” 
  
 Gingrich also vowed to continue in the race even after his distant third place finish. 
  
 “This is clearly still an open race,” Gingrich said in a statement. “So, on behalf of the more than 176,000 Americans who have donated to Newt 2012, I will carry our solution-oriented campaign to Tampa.” 
  
 While all of the candidates made stops here this week — including Gingrich , who stayed in Louisiana for a week — none stuck around to see the votes get counted. 
  
 The absence of candidates in the Pelican State, where 20 delegates are up for grabs Saturday, was likely due to Santorum’s strong showing in the polls in the weeks leading up to the vote. 
  
 It also was the product of Gingrich’s continued slide in the polls, with all indications ahead of Saturday night’s results that the former House speaker might be unable to muster the required 25 percent of the vote needed to qualify for any delegates. 
  
 “I have hopes,” Gingrich told POLITICO of his expectations in Louisiana after a speech Saturday afternoon at the same Pennsylvania conference. He’ll hold no events after the Louisiana results are tabulated, a more common practice for Gingrich after disappointing primary or caucus finishes. 
  
 Gingrich insists he’s not entertaining thoughts that it’s time to get out of the race. 
  
 “The number of people who walk up to me and say please stay in the race is pretty remarkable,” Gingrich said Friday. “I feel a real responsibility to those 176,000 people who have gone to newt.org and donated. … The only pressure I get from anywhere is either Romney supporters or occasional random people in the news media. But people on the street, people at the rallies, people at events like last night at LSU, are very, very enthusiastic.” |||||
Rick Santorum won the Louisiana primary as expected to keep alive his faint hopes for the GOP nomination, reports AP. Santorum easily bested Mitt Romney to rebound from last week's loss in Illinois. But given that only 20 delegates were at stake, tonight's results won't do much to change his near-impossible delegate math. With 99% of precincts reporting, Santorum had 49%, ahead of Romney (27%), Newt Gingrich (16%), and Ron Paul (6%). "We're still here. We're still fighting. We still believe, as this race really shows," Santorum told his supporters in Green Bay. Expect the calls for Gingrich to drop out to intensify, notes Politico: He won't win even one delegate because he failed to reach the necessary threshold of 25% of the popular vote.
