Sen. John Thune (R-S.D.) is traveling to Arkansas to campaign for the Republican Senate nominee.

Thune, often mentioned as a potential presidential candidate, will be in Little Rock on Aug. 24 to stump with Rep. John Boozman (R-Ark.). 

Boozman, who's running against Democratic Sen. Blanche Lincoln (Ark.), said he considers Thune a role model. 

"Senator Thune has been standing up to the Obama-Pelosi-Reid agenda in the U.S. Senate, the exact type of leadership that the people of Arkansas have been demanding from their U.S. Senator," Boozman said in a statement. "I look forward to welcoming him to Arkansas and, ultimately, serving with him in the U.S. Senate."

Thune famous defeated then-Senate Majority Leader Tom Daschle in 2004. He's up for reelection this year but is running unopposed.
