Is Rick Santorum running to be president of part of the country?

After winning the Kansas caucuses Saturday, the former Pennsylvania senator had this to say to supporters, according to the New York Times:

“I kept saying, you just stick with us, you go out and vote for your values and trust what you know,” he told supporters. “Because you don’t live in New York City. You don’t live in Los Angeles. You live like most Americans in between those two cities, and you know the values you believe in.”

What exactly does this mean? People in New York City and Los Angeles are un-American? How about people in Philadelphia, whom Santorum used to represent?

I understand that Santorum, if nominated, is not going to win the electoral votes of New York or California. But if elected, he is going to be president of the United States of America. Apparently the “United” part of that has limited value to him.
