Nader 'Almost 100%' Certain Obama Will Face Primary He's just not sure what the 'stature' of the candidate will be By Kevin Spak, Newser Staff Posted Aug 5, 2011 1:16 PM CDT 54 comments Comments Ralph Nader is seen in Washington, on Thursday, Aug. 20, 2009. (AP Photo/Jacquelyn Martin) (Newser) – The debt ceiling deal has so inflamed liberals that "the chances of there being a challenge to Obama in the primary are almost 100%," Ralph Nader said yesterday in an interview with the Daily Caller. Nader has said for a while that he’s trying to get someone to run against Obama, and after last week, he's sure a Democrat will step up to the plate. He’s just not sure who yet, but he says there will be “another chapter of this effort” in about a week and a half. Nader said the candidate could be “an ex-senator or an ex-governor” or an “intellectual leader or an environmental leader.” One thing’s for sure though, the candidate won’t be Nader himself. “I’ve done my rounds,” he said.
