Arkansas Senate primaries to test anti-incumbent mood

LITTLE ROCK, Ark. (AP) - The results of the Democratic and Republican primaries for a United States seat in Arkansas on Tuesday may show just how deep anti-incumbent sentiment is among voters this year.

Democratic Sen. Blanche Lincoln and Republican Congressman John Boozman, the front-runner for the GOP nomination for her post, are both being targeted by candidates touting an anti-Washington message.

For Lincoln, it's meant fending off a challenge from Lt. Gov. Bill Halter in a multi-million dollar fight for the Democratic nomination that's attracted some of the nation's largest special interest groups. Boozman has enjoyed a comfortable lead in most polls, but he's increasingly being criticized by two candidates aiming for at least a spot in a June 8 runoff.
