Matt Yglesias calls it like it is:
Back in October 2007, Clinton was beating Obama in Maine by a hilarious 47 to 10 margin, but it seems he's carried the state today, once again by a large margin. My understanding, though, is that this doesn't really count because it's a small state, much as Utah doesn't count because there aren't many Democrats there, DC doesn't count because there are too many black people, Washington doesn't count because it's a caucus, Illinois doesn't count because Obama represents it in the Senate even though Hillary was born there, Hawaii won't count because Obama was born there. I'm not sure why Delaware and Connecticut don't count, but they definitely don't.
Time killed Napoleon at Waterloo (with an assist from Grouchy) and in 1812; time is going to kill Hillary in 2008. Each passing day chips away at the rationale, the entire premise, of her campaign. Sad for her, but that's life.
