I have some theories and guesses.
But I don't know as there is a single cause rather than combined multiple causes.
One of them being communists.
It still absolutely frosts me that people as stupid and morally insipid as Ted Kennedy, Harry Reid, and Howard Dean aren't laughed off the stage with each pronouncement.
Instead they keep voting them in.
Sorry, if I started ranting, my computer would burn up and arrest me......
