Well, that didn’t take long.

Newt Gingrich’s top staff quit en masse Thursday, throwing into question whether his already troubled presidential campaign can continue.

Two sources close to the situation confirmed that campaign manager Rob Johnson, strategists Sam Dawson and Dave Carney, spokesman Rick Tyler, and consultants Katon Dawson in South Carolina and Craig Schoenfeld in Iowa have all quit to protest what one called a “different vision” for the campaign.

The sources said Gingrich was staying in the race.

The mass resignation was, one source said, “a team decision.”

I had previously said that Mr. Gingrich’s campaign would be over by the All-Star Break, then Memorial Day. Let’s settle on the Fourth of July.
