Florida has now taken the lead, Pennsylvania has fallen to 3rd place after Texas.
Why do we care about Texas? It won't even be competitive unless Obama already has >57% of the national popular vote. Even the senate race is a shoe-in for whichever R wants to replace KBH barring a major scandal.
It could show whether the Obama Administration is gaining in some of the states that he lost by large margins. If Obama has been gaining in Texas what he has been losing in some Northern states, then that could show a lessening of interstate polarization.
Of course, both Pennsylvania (despite a Quinnipiac poll) and Florida would be far more interesting.
Pennsylvania can probably be colored red now. None of the imaginable GOP nominees has any connection to Pennsylvania. If they would all lose in Ohio, they would also lose in Pennsylvania.
