This may sound a little strong, but I consider those who voted for Obama a second time (2012) to be enemies of democracy, hence they're enemies of this country. I'll cut them a little slack for '08, since much of the country had Bush Derangement Syndrome and got caught up in Obama's hopey-changey schtick. But, to willingly vote for him again, AFTER seeing the havoc he was wreaking is unforgivable.
I look at Obama supporters as enemy because they are just that.
