How can I get the latest state-by-state presidential polls?

[elperromagico]

We hear so much here about national Bush v. Kerry matchups, but as a lot of us learned from 2000, an election is won or lost in the individual states. At least 30 states won't even be "in the race," so to speak; they're essentially guaranteed to be highly partisan.

I'm a poll junkie, but I'm not terribly interested in national polls for the reasons I stated above. Where can I get state-by-state matchup polls? I've checked the Web and I've found a few resources, but they're so out of date it's basically pointless to predict anything based on them.

Any help would be appreciated. :)
