Nader now says that a primary challenge is a near certainty.

"What [Obama] did this week is just going to energize that effort," Nader promised in an interview with The Daily Caller. "I would guess that the chances of there being a challenge to Obama in the primary are almost 100 percent."

The only question, he said, is the stature of that opponent and whether it will be either "an ex-senator or an ex-governor" or "an intellectual leader or an environmental leader."

In approximately a week and a half there will be "another chapter of this effort," Nader predicted.

The Public Citizen founder said he disapproved of how Obama handled recent debt ceiling negotiations, and claimed the deal's failings prompted this week's dramatic stock market drop.

"He made a deal that did not provide for a public works project to create jobs all over the country. All he did was he agreed to cut spending," Nader said. "And that's what the market is reacting to."
