Toomey could also have picked up votes in the Philly suburbs, which, althought they're pro-abort, they do prefer low taxes. Toomey was good at delivering that message. Except for Chester County, Bush lost the Philly burbs, but still ran it close. Some crossover from there would have put Toomey over the top.
Good point. Toomey makes a great appearance, and is a good communicatior.
