 Democratic Rep. Kyrsten Sinema took a narrow 9,610-vote lead over GOP Rep. Martha McSally Thursday evening as Arizona’s election authorities counted more ballots in the state’s uncalled Senate race. 
  
 The lead amounts to less than half a percentage point with more than 1.8 million votes counted. McSally was up by 17,703 votes earlier in the day, before the counties processed another 160,000 votes — but about a half-million more votes remain to be counted across Arizona, according to both campaigns.

 Most of the outstanding ballots are coming from Arizona's largest county, Maricopa County, which is home to Phoenix and includes Sinema's congressional district. Sinema held a slight edge of about 1 point over McSally in the county as of Thursday afternoon, but the new votes counted Thursday expanded the Democrat’s Maricopa edge to 2.5 points. That’s the outcome Democrats had hoped for, while Republicans were expecting McSally’s tally there to improve. 
  
 The state will continue to count early votes cast before the election daily until the race is resolved. 
  
 “Arizonans must have faith that their votes are counted, and we are working diligently to ensure that count proceeds in a fair, transparent, and timely manner that voters can trust,” Andrew Piatt, Sinema’s campaign manager, said in a statement Thursday afternoon. He said he was confident Sinema would prevail once the remaining half a million votes are counted.

 "With half a million ballots left to count, we remain confident that as votes continue to come in from counties across the state, Martha McSally will be elected Arizona's next senator," McSally campaign CEO Jim Bognet said in a statement. 
  
 Arizona is one of three remaining Senate races without a declared winner. In Florida, Republican Gov. Rick Scott is ahead of Democratic Sen. Bill Nelson by two-tenths of a percentage point, but the race is headed for a recount. And in Mississippi, Republican Sen. Cindy Hyde-Smith and Democrat Mike Espy will face off in a late November special-election runoff. 
  
 Republicans have already secured 51 Senate seats to 46 for Democrats, after three Democratic incumbents and one GOP senator lost on Tuesday night.

 Hyde-Smith is expected to win the Mississippi runoff. But depending on the results in Arizona and Florida, the Republican majority in the next Senate could be as small as 52 seats or as big as 54. That spread could be significant on legislation and judicial confirmations over the next two years — as well as in the 2020 elections, when Republicans must defend 22 Senate seats compared to just 12 for Democrats. 
  
 In Arizona, Sinema led comfortably in polling throughout the summer and fall, but McSally closed the gap by late October. The race was one of the most expensive in the country, with nearly $30 million spent by both parties. 
  
 Sinema and McSally are vying to replace Republican Sen. Jeff Flake, who retired after clashing with President Donald Trump. 
  
 Both campaigns are digging in for a protracted coda to the election. McSally’s campaign sent out a fundraising request Thursday evening for donations to help fund an “army of attorneys and observers” to fend off any legal challenges once the votes are tallied. 
  
 McSally’s campaign also tweeted that she was “dreading a long and painful process.” The tweet included a photo of her in a dentist’s chair. ||||| CLOSE Hundreds of thousands of votes are still left to be counted.

 Suspense and uncertainty now hang over the supertight U.S. Senate race, which has Democrat Kyrsten Sinema and Republican candidate Martha McSally separated by just 9,610 votes, according to updated election results. 
  
 The results were updated after 5 p.m. Thursday, the first time since election night that the tallies had been substantially updated. 
  
 Sinema was leading as of 6:20 p.m. She had 932,870 votes,representing 49.10 percent of the total reported votes while McSally had 923,260 votes, or 48.59 percent. Green Party candidate Angela Green had earned 43,838. 
  
 It's too soon to know who will ultimately prevail. 
  
 With tens of thousands of outstanding ballots, the campaign managers for both teams conveyed confidence, with each saying the remaining ballots would favor their candidate. 
  
 After Sinema's lead widened Thursday, McSally's campaign manager, Jim Bognet, predicted Sinema's lead would "disappear." In a written statement, he said outstanding ballots in Maricopa County arrived on days when early GOP turnout was higher than the votes reflected in Thursday's results. 
  
 "With half a million ballots left to count we remain confidence that as votes continue to come in from counties across the state, Martha McSally will be elected Arizona's next Senator," Bognet said in the statement. 
  
 Sinema and McSally are no strangers to the drama surrounding extended vote counts. 
  
 It was election night 2012, and Sinema was sequestered in a hotel room with a dozen or so supporters, friends and campaign staffers in a makeshift war room. 
  
 It was her first bid for Congress and her campaign didn't have the money to splurge on a business suite. The bed ate up most of the floor space, strewn with papers, charging cords and laptop computers. 
  
 The early election results dropped at 8 p.m. that election night six years ago. She was ahead of Republican challenger Vernon Parker, just not as much as she had hoped to be in the race for Arizona's 9th Congressional District, a newly created seat evenly divided between Republicans and Democrats. 
  
 Sinema buzzed with nervous energy and settled in for a roller-coaster week. 
  
 Her lead began to grow over the course of the few days, as the Maricopa County Recorder's counting of so-called late early ballots began to post, recalled her former campaign manager, Rodd McLeod.

 As she awaited the final results, Sinema threw a party for the volunteers and staff who worked on her campaign and worked the phones, thanking donors and supporters. 
  
 "She understands there's a big job to do counting these ballots," McLeod said. "You're still working, and you're observing the ballot count, but you're waiting. You're letting people know you appreciate their hard work." 
  
 On the Friday after Election Day, she got a concession call from her GOP rival.

 The candidates and their Democratic and Republican allies have built out sophisticated models that analyze the geography of outstanding ballots, past voting behaviors, and voters' party affiliations. 
  
 But they are riding the same emotional roller-coaster as the estimated 2.3 million voters who will have decided the race.

 And then there are the legal challenges, which could prolong the result for weeks as either side works to disqualify or add voters to the rolls in the event the final margin reaches below 5,000 or so. 
  
 Already, Republicans were in court Thursday to dispute a practice used by certain counties to verify mismatched signatures of early ballots. 
  
 About 90 minutes before state elections officials were scheduled to post an updated ballot tally, Sinema's campaign manager, Andrew Piatt, sought to manage the public's expectations about Thursday's posting. In a statement, he predicted if all votes are counted, Sinema will be the next senator. 
  
 "Arizonans must have faith that their votes are counted, and we are working diligently to ensure that count proceeds in a fair, transparent, and timely manner that voters can trust, Piatt wrote in a statement. "To that end, we have spent the hours since the polls closed tracking down ballots and know there are more than 600,000 left to be counted across the state. 
  
 "We also know that when the Maricopa County Recorder releases its first batch of ballots this evening, there will still be approximately half a million votes left to count," Piatt continued. "Once they are counted, we are confidentthat Kyrsten Sinema will be the next Senator for the state of Arizona.” 
  
 McSally, a former U.S. Air Force combat pilot, has also been here before. 
  
 In 2012, she lost a primary election against former Marine Jesse Kelly to run in a special election to fill the remaining months of former Rep. Gabrielle Giffords' term in Congress. 
  
 Two years later, she edged out Democratic Rep. Ron Barber by only 167 votes to win the Tucson-based 2nd Congressional District — but only after a recount and legal fights, which she has frequently talked about on the campaign trail in her race for the Senate. 
  
 That race, like the Senate race, was a key battleground for outside spending groups and blistering attack ads against both candidates. 
  
 In the end, McSally unseated Barber by a razor-thin 167 votes out of an estimated 220,000 cast.

Output:
Democratic candidate Krysten Sinema has edged ahead of Republican rival Martha McSally in Arizona, one of three states where Senate races are still undecided. The state's first major update since election night said Sinema was leading with 49.10%, or 932,870 votes, while McSally was at 48.59% with 923, 260 votes, the Arizona Republic reports. With around 500,000 votes still to be counted, the campaigns of both candidates vying to replace Republican Sen. Jeff Flake released statements expressing confidence that their candidate would prevail. The Senate race in Florida is headed for a recount and the Mississippi race will be decided in a runoff election later this month, Politico reports. (The midterm elections brought 49 out of 50 state legislatures under single-party control.)
