Kaine: No serious 2012 primary challenge to Obama

WASHINGTON — The national Democratic Party chairman says he thinks the chances that President Barack Obama will face a serious primary challenger in 2012 are "virtually nil."

Tim Kaine says there's always the possibility that a fringe candidate could try to mount a challenge. But Kaine says Democrats feel very good about Obama's re-election prospects if, as Kaine puts it, the president keeps doing the job that people elected him to do.

Kaine also told CNN's "State of the Union" on Sunday that he expects to continue as party chairman for another two-year term.
