Paddy linked me to this:
Paul Kane: I've spent the past several months talking to as many super-delegates as any reporter in America, I'd guess, since I cover on a day-to-day basis about 280 of them here on Capitol Hill.
I hate saying this, because all the Clinton people are going to flip out and say, You're biased, you're biased, you're biased. So go ahead and flip out if you want, but the simple basic truth is that the super-delegates stopped paying attention to the Clinton-Obama race about a couple days after the Indiana and North Carolina primaries.
They've stopped paying attention to the primary, and instead they're focused on an Obama-McCain matchup in November. That's the basic, simple, definitive reality that has happened in this race. The "undecided" super-delegates at this moment are not going to "decide" any time soon, because to them the race is over, they're just waiting for Clinton to drop out.
I'm working on a McCain post, so I'm copying and pasting this one in full. Have fun with it.
