I've never been persuaded by the argument that Democrats are mostly electoral victims of their relative lack of expertise at politics--that they would win every election if it weren't for the fact that Republicans are just badass, nasty, down and dirty campaigners.
But boy, Obama and Hillary do seem determined to prove that Democrats do so shoot themselves in the foot!
I look at that debate and it seems to me that Democrats think they can't lose in November--that the only important battle is the one for the nomination. Yet if this goes on much longer, the chances rise that the nominee will hobble, crippled, into the November elections. Obama's supporters probably won't vote for McCain if Hillary is the nominee, but they might well stay home if they think that she slimed her way into the nomination. And all the sniping is just upping everyone's negatives and providing the Republicans ammunition for November. My original prediction of a 95% chance that Democrats take the White House in November is being revised downward, fast.
