Despite winning the New Hampshire primary, John McCain is still not popular among Republicans. Ramirez illustrates why:
A lot of conservatives will vote for him if he's the nominee, but very few will be enthusiastic about it.
Who will benefit most among the Republicans if any of the top five decide they can't continue? Which of the remaining candidates will their supporters gravitate toward? It isn't at all clear at this point.
On the Democrat side I would think that Hillary wants Edwards to stay in the race as long as possible because when he gets out, which seems inevitable, his supporters will likely swing to Obama. I don't know that Mrs. Clinton's candidacy, much less her ego, can withstand that.
The next three weeks will tell, probably.RLC
