On Tuesday, voters will finally decide between Bill Halter and incumbent Sen. Blanche Lincoln as the Democratic nominee for one of Arkansas's Senate seats (some are already deciding, since early voting has started).
Lincoln, who's nearing the end of her second term, came under fire when she helped squander a Democratic supermajority that could have led to more progressive health-care legislation, among other things. So MoveOn.org and labor unions like the AFL-CIO backed Halter, who is the state's lieutenant governor. On May 18, when the first vote was held in the primary, Halter and a third candidate, conservative D.C. Morrison, siphoned off enough votes to keep Lincoln from getting an outright majority, forcing a runoff.
