Three-quarters of Arkansas's House members are considering a run against Sen. Mark Pryor, a sign the centrist Democrat will face a tough race in 2014 in the red state.

Reps. Tim Griffin and Steve Womack and Rep.-elect Tom Cotton all told a local paper in a paywalled story that they're mulling runs against Pryor.

None committed to the race, and the GOP field could be unclogged by any of the three making a decision to run for governor in a state that has trended Republican in recent years. Before the 2010 election, three of the state's four congressmen and both of its senators were Democrats. Now Pryor is the only Democrat left in the congressional delegation.
