Arkansas Lt. Gov. Bill Halter (D), who's challenging Sen. Blanche Lincoln, spoke with RealClearPolitics yesterday -- one day after announcing his bid. Halter struck a populist tone during the interview, and showed that he will be highlighting his signature piece of legislation, the state scholarship lottery, throughout the campaign.

When RCP noted that it's pretty rare for an incumbent senator to lose a primary, Halter responded: "In terms of the ability to go out and win -- this is why you have campaigns. You go out and you take your issues to voters, and you put them out there and people respond or they don't. But so far they are responding extremely well."

Halter has some fundraising to do, though he reportedly already has significant fundraising pledges from progressive and labor groups. Lincoln had $5 million in the bank at the beginning of the year.
