LITTLE ROCK (AP) — Arkansas' chaotic political scene may finally settle down next week, as the state prepares to kick off the filing period for public office.

With three of the four state's sitting congressmen bowing out of re-election bids and Sen. Blanche Lincoln facing a tough re-election fight, uncertainty has dominated Arkansas' politics this year. Leaders of both parties say many of the questions dominating political talk in the state will be answered during the one-week filing period, which begins Monday.

The biggest question surrounds Lt. Gov. Bill Halter, who has been raising money for a re-election bid. Halter, a Democrat, has also left open the possibility that he'll run for a congressional seat in central Arkansas or challenge Sen. Blanche Lincoln in the party primary.
