Johnson Candidacy a Threat to Lincoln

LITTLE ROCK, Ark. (AP) - Bob Johnson's flirtation with a bid for the U.S. Senate is a chancy move for a lawmaker who contends he's not well known beyond his legislative district. It's also another threat that U.S. Sen. Blanche Lincoln doesn't need as she seeks a third term in office.

The Arkansas Senate president's announcement that he's considering challenging Lincoln in next year's Democratic primary is the latest surprise move from a state legislator who has made unpredictability one of his hallmarks.

Republicans have been increasingly eager to paint Lincoln as vulnerable in next year's election, pointing to public opinion polls showing weak approval numbers in the state.
