He's not delusional. I have first hand experience. A coworker of mine who is extremely conservative, but not terribly well-informed, told me excitedly about this new Obama guy who he thought was a great speaker. Once I informed him of some of Obama's more extreme liberal opinions he almost got sick.
The point is, just because someone is conservative doesn't mean that they can't be misled by a good salesman (Obama.) As a matter of fact, it's getting easier and easier as people can tell you all about American Idol, but can't name their own Senators.
Thank you for being there to set him straight. Good grief.
