Based on the barrage of television ads and mailers leading up to Tuesday's primary election in Arkansas, it's obvious who the most influential Republicans in the state are.
Tom Cotton's making the case for fellow Sen. John Boozman, talking up his conservative bona fides while the two-term senator fends off challenges from the right. Donald Trump's image appears in ads for Boozman and for Sarah Sanders, who served as the former president's White House press secretary and is now running for governor. Sanders, whose endorsement is almost as sought after as Trump's, is helping make the closing argument for Boozman in a TV ad.
