Clinton basically overwhelmingly won the urban vote. I daresay the urban vote has a different mentality than the rest of the country.
Also, those who say that she won the popular vote as if that has some special meaning, only need look again and see that she only won it by the slimmest of margins (about 230K out of a voting age population of 245M)
She only won the popular vote because NON citizens are voting. Just saw something here on FR that 13% of illegal aliens in California voted. That would be around 1 milllion illegal votes right there.
