If Obama is the anti-christ and he DOESN'T win the election (take power), then we will never get to experience the glorious Armageddon the Bible promises which will trigger the second coming of Jesus and that would mean all those who preached that the book of Revelations was a prophecy were wrong and it will be John McCain's fault that Jesus didn't come back to snatch you up!!.
So you MUST vote for Obama if you want to see Jesus and who knows, he might just be the best president this country has ever seen. EVIL GRIN
(Feel free to use this logic if you encounter any who actually believe O is the anti-christ(WTF). It has blown the minds of the few I have encountered haha.)
