I don't know, my dad is in his 70s and is one of those democrats who (I think) mostly votes republican now since the dems went all lefty on him. But I mentioned I was wondering why the polls show that Obama, who's done nothing, is getting benefit from the financial crisis. And he said "Because he's damned smart! He went to Harvard Law!" I was taken aback a bit, since my dad was one of those who wanted a guy like McCain, he thinks Bush screwed things up and he thinks Bush is a conservative (!) so he wanted a moderate. But now he is leaning towards Obama. Man, that upset me.
Send you dad the articles FRom the Thomas Sowell thread. Those will change his mind.
Tell your dad about the nationalized health care system which will come under an Obama administration. Then show him this article to impress upon him what happens when you go to a national health care system like the UK has.

If he still wants to vote for Obama, well that would be a sign of dementia, now wouldn't it? ;)
