This is true, but it can't be the only reason leftists seem to occupy huge chunks of the East and Left coasts.
I've often wondered why much of our nation's prime oceanfront real estate is occupied by leftists. How did this happen?
Part of the answer is that two-income, childless "families" -- gays and childless couples -- moved into neighborhoods, gentrified them, and drove housing prices up so high that traditional families couldn't afford them.
I know this has happened in many neighborhoods in San Francisco.
