Well, if you know your history, San Francisco was a solid Republican city, with an uninterrupted string of Republican mayors before WWI to the mid-1960s. Then liberals flooded in from everywhere else and changed everything. This also happened to the state of California around the same time. Some of those liberals then returned home and spread their "ideals". The problem is not where liberals are coming from, but that their "ideals" are spread to others without an effective deterrent. Time to brew up a DDT to stop the liberal disease!
Trust me, I don't believe it. But if you listen to Ron Paul, the government may tried brewing up a DDT for one reason or another.
Ron Paul's newsletters. The gift that keeps on giving.
