Kos has the most recent poll numbers. Anyway, it's way too early to count any of the 4 out (that Joementum only goes one way). I retract what I said about Clark being "wounded" last night. He's as in as much as Edwards is. I reject all claims that this is over. I reject that any candidate "has to win" any particular state at any particular time, and I also think wondering out loud about a possible brokered convention is silly.
We've had 2 of 50 primaries...
...I'd say the Poor Man's nomination odds are roughly right.
