ROBERT SIEGEL, HOST:
Now to a Senate race in which a Republican incumbent faces a challenge from the right. Senator Lamar Alexander of Tennessee is running for his third term and among his challengers in next month's GOP primary is candidate who's backed by the Tea Party. Tea Party groups in Tennessee are optimistic. But as NPR's Brian Naylor reports they still face an uphill battle.
BRIAN NAYLOR, BYLINE: Joe Carr's campaign office is just across the street from Murfreesboro's antebellum courthouse. An American flag hangs out front and in the window a big campaign sign calls on Tennessee Republicans to, vote for Carr not Lamar. Inside young volunteers are calling potential GOP primary voters.
CHELSEA: Hi, my name is Chelsea (Ph) and I'm a local volunteer with some quick questions if you have a few minutes.
NAYLOR: Joe Carr a 56-year-old state representative says there are a lot of reasons why conservatives have soured on Alexander.
JOE CARR: His voting record, whether it's on raising taxes or voting to get (Unintelligable) Obamacare or voting for amnesty or embracing the war on coal. Over and over and over again Lamar Alexander has shown a willingness to work with the other side, instead of standing with our side.
NAYLOR: Carr has won endorsements from Tea Party groups nationally and in Tennessee. And he has the backing of conservative talk show host Laura Ingraham, as the influx of children across the southern border became front page news. Carr ran an ad attacking Alexander for backing amnesty.

CARR: President Obama created this crisis only after Lamar Alexander voted for amnesty. He is responsible. I'm state representative Joe Carr.
NAYLOR: But, while Carr has corralled endorsements, Tea Party groups have not been opening their checkbooks for him. Still Ben Cunningham, President of the Nashville Tea Party, hopes that won't be necessary.
BEN CUNNINGHAM: You're not going to outspend them and ultimately money doesn't vote. We're just going to work it as hard as we can, get the message out. If we do that well enough I'm convinced that Joe Carr has a real shot at defeating Lamar Alexander.
NAYLOR: But while money may not vote it does buy you a lot of TV ads and a lack of it, especially for a relatively unknown candidate like Carr, makes it hard to get your message out. Alexander has some 3.4 million dollars on hand in the final weeks of the campaign. Nearly eight times what Carr has reported. Alexander's been using some of that money to run ads that show him standing up to President Obama during a 2010 healthcare forum.
(SOUNDBITE OF POLITICAL AD)
PRESIDENT BARACK OBAMA: Lamar when you mentioned earlier that you said premiums go up that's just not the case.
SENATOR LAMAR ALEXANDER: The Congressional Budget Office report says that premiums will rise.
OBAMA: No, no, no, no.
NAYLOR: Unlike some other Republican incumbents who have faced Tea Party challengers. Alexander has taken steps to stay in touch with Tennessee voters. He returns home frequently, he rounded up support from all the state's Republican county chairs and he gave up his post in the GOP Senate leadership. Bruce Oppenheimer teaches political science at Vanderbilt.
BRUCE OPPENHEIMER: Alexander if you remember was a part of the Republican Senate leadership but stepped down from that leadership. And I think he thought that that was probably not going to be - serve him well.
NAYLOR: Alexander has served Tennessee as public figure since the 1970, including two terms as governor in which he famously campaigned walking across the state wearing a red plaid shirt, as well as two runs for president. The 74-year-old Alexander says he still runs into voters in whose homes he spent the night on those previous campaigns and he appears confident about next month's primary.
ALEXANDER: Tennessee is accustomed to having good rowdy open political primaries and I've run in several of them and I welcome the opportunity to go back to the people of Tennessee and try to re-earn their trust. And - I'm a conservative with an independent streak, who likes to try to get results.
NAYLOR: There are other factors working in Alexander's favor, a crowded field of opponents, that along with Carr includes George Flinn a wealthy radiologist who has spent millions of his own money on previous runs for Congress. And unlike other Southern states there is no runoff in Tennessee, even if Alexander falls short of 50 percent, he need only outdistance his opponents and he'll be on the ballot in November.
