Halter, Lincoln in furious fight for Arkansas Senate

LITTLE ROCK, AR (AP) - The fight for the Democratic Senate nomination in Arkansas has turned into a pitched battle between 1 of the most vulnerable incumbents in the country and a challenger backed by some of the groups on the left that she's angered.

The unknown factor in the race between Sen. Blanche Lincoln and Lt. Gov. Bill Halter is whether a third candidate - D.C. Morrison of Little Rock - could force a runoff on June 8 by siphoning off enough votes.

Lincoln has presented herself as the victim of special interests on the right and the left. She tells audiences that she is the rope in the tug of war.

Halter, a one-term lieutenant governor, has the backing of labor unions and other groups that said they grew dissatisfied with Lincoln. He said during a debate last month that the unions felt Lincoln had turned her back on working men and women in Arkansas.
