One of the Senate's liberal leaders said Wednesday that it would be beneficial for President Obama to face a primary challenger from the left in 2012.
Sen. Bernie Sanders (I-Vt.), who has criticized the president for — among other things — brokering a tax deal with Republicans, said that it is worthwhile to have a wide array of voices in the campaign.
Sanders's comments could revive talk of a primary challenge to Obama; many observers speculated that could happen after Democrats took a beating in the midterm elections, making the president look vulnerable for reelection in 2012.
But Obama's poll numbers have rebounded since then, leading elections handicappers to say his reelection chances look stronger than they did three months ago.
Still, Sanders said that a challenge would be a positive thing for the Democratic field.
"In a democracy, I think it's worthwhile to have different voices
out there," he said.
Sanders was one of the politicians talked about as a potential primary challenger in December after he spent eight-and-a-half hours on the Senate floor railing against Obama's tax-cut deal.
The self-described democratic socialist again ruled out a run Tuesday after he did so at the end of last year.
"I'm not a Democrat, I'm the longest-serving independent in Congress," he said.
A number of other potential candidates, including former Sen. Russ Feingold (D-Wis.) and Rep. Dennis Kucinich (D-Ohio), have also said they will not run.
