According to NBC and ABC News, Bill Clinton began a speech in South Dakota today saying (video here):

“I want to say also that this may be the last day I’m ever involved in a campaign of this kind. I thought I was out of politics, ’til Hillary decided to run. But it has been, one of the greatest honors of my life to go around and campaign for her for president.”

Does this signal the beginning of the end for Hillary Clinton? The Atlantic’s Marc Ambinder offers some other telling clues here and here. Of course, Clinton aides deny that she’ll drop out tomorrow.

Meanwhile, USA Today reports: “Hillary Clinton has sent out a fundraising pitch called “The last two races,” asking people to contribute $5 to help her get out the vote tomorrow in South Dakota and Montana.
