Here’s the clearest signal I’ve yet seen that John Edwards should drop out of the Presidential race and concentrate on retaining his North Carolina Senate seat:

The other candidates are Sen. John Edwards of North Carolina, Rep. Dennis Kucinich of Ohio and former Sen. Carol Moseley Braun of Illinois.

That’s a paragraph toward the end of Newsday’s wrapup of yesterday’s debate among Democrats.

In other news, it seems Howard Dean didn’t turn in a great performance at the debate. He needs to be more scrupulous about being consistent if he wants to win.
