John Podesta: For Hillary Clinton, a Matchup With Donald Trump ‘Works Very Well’

The chair of Hillary Clinton's campaign appeared on "This Week."

The three remaining Democratic candidates spoke Saturday night at the Jefferson-Jackson fundraising dinner hosted by the Iowa Democratic Party in Des Moines. Podesta said he detected a shift in Sanders' rhetoric.

"I think Bernie Sanders seemed to have a course correction in the JJ dinner from one in which he said he wasn't going to go negative to -- to obviously focusing his, you know, his fire on her," he said.

Clinton's performance before the committee earned her widespread praise. Former Obama campaign strategist David Axelrod said on Friday that Clinton performs best when her back is against the wall, but added that she should be cautious to "not settle back into the posture of the cautious, calculating frontrunner."

When asked about that critique, Podesta said Clinton's experiences in the 2008 campaign "convinced her that you've got to keep your nose to the grindstone every day, fight for every vote, tell people what you want to do for them, what the future could look like if they elect you."
