So, in other words, the PA gambit is useless...
I reserve the right to change my mind but, yeah, probably. The structural advantage that the Democrats have in that state just seems too large for McCain to have any hope of overcoming in an election like this. The word "gambit" says it all, really. Especially as we aren't in the opening stages of the game anymore...
You're probably right on PA, but who knows. On the list, it's the state I'm least sure about being solid colored (maybe WI too, since the polling there is always questionable, but the Dems have an even better built-in advantage). I also question the gray on AZ and AR, but it's not a biggie.
