Aboard the Tea Party Express (CNN) -- From the stage, Deborah Johns is the angry conscience of the tea party movement.



A protester uses a Nazi swastika to make a point at a Tea Party Express stop in Dallas, Texas.



"Question everything your government is doing," she tells a crowd of about 100 from the bus's stage in the parking lot of the Winners casino in Winnemucca, Nevada.



Under a setting sun on the steps of the state capitol in Little Rock, Arkansas, Johns says: "Our men and women took an oath when they put on the uniform to defend and protect this country from enemies both foreign and domestic. I think we've got some domestic enemies in the White House."



On a sunny afternoon in Louisville, Kentucky, Johns works the crowd of about 2,000 into a frenzy.



"The men and women in our military didn't fight and die for this country for a communist in the White House," she says, and the crowd erupts in a chant of "U-S-A, U-S-A!"  Watch rally participants converge on Washington »



On the bus, Johns slips off her heels and slips on a pair of ankle socks. She curls up under a quilt her grandmother made. She favors skirts and cardigans -- a pit bull in cashmere.



She leads the rallies in each city with Mark Williams, a former talk radio host who now writes books and makes the rounds on cable TV chat shows. Both work for Our Country Deserves Better, the conservative political action committee sponsoring the Tea Party Express bus tour.



The tour concluded Saturday at the U.S. Capitol in Washington after a 34-stop tour that began August 28 in Sacramento, California.



Williams is the showman of the bunch. His signature line when he gets the mic goes like this: "You can have our country when you pry it from our ... cold ... dead ... fingers!" Again the crowd erupts.  Watch scenes from Tea Party Express rallies »



Seldom seen on stage are the two gurus of the tea party movement, veteran politico Sal Russo and his protégé, Joe Wierzbicki. They are charged with turning the passion on display at the tea parties into political action.



They have three goals: Defeat President Obama's health care reform efforts, win back the House and Senate in 2010 and take the White House in 2012.



Russo grew up in a house full of working-class Democrats in Monterey, California, and nearly gave his father a heart attack when he became a Republican. His first paid gig in politics was working for Ronald Reagan's 1966 California gubernatorial campaign, and he has worked in conservative politics ever since.



Russo often watches the raucous tea party events from his perch in the bus. Besides Johns and Williams each event features several musical acts and featured speakers.



The crowd is its own sideshow. Tea partyers are a creative lot, and many in the crowd express themselves by way of their clothing and signs.  See some of the getups and signs »



"Obamacare Condense Cream of Crap soup" reads a sign in Sparks, Nevada. In Dallas, Texas, a darker mood prevails. A homemade sign with "Obama Lies" features a bold, black swastika.



As the tour moves on, Nazi imagery becomes more prominent -- and sometimes confused. One sign at the Alamo in San Antonio, Texas, has Obama's portrait sandwiched between pictures of Adolf Hitler and communist philosopher Karl Marx. In Canton,Ohio, Obama and Hitler adorn a sign reading "Hitler made great speeches, too."



In Elko, Nevada, over a Basque supper of oxtail, lamb and sweetbreads, Russo assesses the tea party movement.



"There are some people who are mad at everyone," he says, "but there are others who say, 'How do we move beyond this and turn it into action?'"



Rare is the conversation with Russo in which he doesn't bring up the name of his idol and one-time boss, Ronald Reagan. But if there is
