Famed consumer advocate Ralph Nader, who’s run for president a few times himself, would like to see Maryland Gov. Martin O’Malley (D) make a bid for the 2016 Democratic nomination.

During an appearance this week on Fox News Talk Radio, Nader said “it’s very bad for the Democratic Party to start a coronation of Hillary Clinton.”

“Because what happens if she stumbles and there’s no one else known to take her place?” Nader asked talk-show host Alan Colmes. “So I’m for a Governor O’Malley of Maryland following through on his declaration to others, including me in a meeting I had with him about a year ago, that he was not intimidated by Hillary Clinton and he’s going all the way for the Democratic nomination.”

“He’s credible in a lot of areas,” Nader said of O’Malley. “He may surprise people.”

O’Malley spokeswoman Lis Smith confirmed Saturday that O’Malley and Nader have met, but she declined to elaborate.

O’Malley has said he is preparing for a possible White House bid regardless of whether Clinton runs. O’Malley recently told The Washington Post that he will “probably” have decided whether to move forward with a presidential run by the time his tenure as governor ends on Jan. 21.

Nader is a five-time candidate for president. He was a write-in choice in the 1992 New Hampshire Democratic primary, the Green Party nominee in 1996 and 2000, and an independent candidate in 2004 and 2008.
