Keystones

One has to wonder if the Biden selection has more to do with Pennsylvania than Delaware. The Obama camp may be hoping to secure the Keystone State on the electoral map, even though PA isn't really that much competitive than Michigan and certainly less so than Virginia. Last carried by a Republican in 1988, the Bush campaign poured substantial resources into PA in both 2000 and 2004 (particularly 2004) without success; however, the strategy did force the Democratic nominee to respond in kind, devoting resources to a state that otherwise would not have been competitive.

Of course, if Obama needs Biden to win PA, he's in bigger trouble that his media surrogates are allowing to be portrayed...especially if he gives more speeches like this (sorry, I had to post this again...)
