True enough. But, as citizens I believe we have the duty to protect and defend the Constitution from all enemies domestic and foreign. Obama fits that definition in my book.
Hyperbole.
If you really believed Obama was an 'enemy' of the U.S., you'd be calling for him to be brought up on charges of treason.
Trying to turn this election into a 'if you don't vote for McCain, you're voting for the enemy' is predictably juvenile.
