My understanding of one of the reasons for electors is that they were to have final say because many Americans at the beginning of our nation weren’t educated enough to make good decisions. Sadly, that still applies. Perhaps the only reason the Electoral College is still around is the other reason, to balance small states vs. large ones. Electors can vote however they want, although they usually appear to echo their states’ majority vote.
I bet Obama would send his thug lawyers after any elector that didn't play ball. Didn't I hear somewhere that all these law suits were dismissed? The one on this guys web page was just filed 11-1-08.
