Edwards ends his campaign.

John Edwards will officially announce the end of his campaign at noon today.

Of course, the big questions now are 1) will he endorse either remaining candidate, 2) if so, who, and 3) when?

If he wants to have an impact on Super Tuesday, I would expect an endorsement today. There had been talk before that he would stay in the race in order to play king maker or queen maker at the convention. However, now that he is out of the race, his chances of playing such a role decrease. It seems to me that he could have the biggest impact by making an endorsement now. As I said on Monday, I think the campaign might have reached a tipping point Monday with the Ted Kennedy endorsement of Obama. Edwards endorsing Obama today could really tip things in Obama's favor. On the other hand, Edwards endorsing Hillary could restore balance or tip things in her favor. In any event, it would greatly slow the momentum that Obama has been gaining lately.

So who might Edwards endorse? Judging by his basic campaign themes, debate performances, and his recent comment that Democrats have to choose a nominee that can win in November (as opposed to simply winning party primaries), I would think he would endorse Obama. But who knows?

Stay tuned...
