Many other Northeastern states are in the same situation as Pennsylvania. Voters in a few big cities tip the elections towards liberals. If you take out just a few urban areas from the 2012 election results Republican candidates would have won in a landslide. Here in New Hampshire many towns reliably vote Republican, but a few bastions of students and liberals in cities outnumber the rural residents.
What the fools in the cities forget is that they depend on the rural areas for everything the eat, their energy, and much of what they purchase in stores.
Our Founding Fathers were right in allowing only property owners the right to vote.
Letting ubran takers vote is like handing liquor and the car keys to 15 year old boys.
