If these two nasty e-mail messages are any indication, the 2008 presidential campaign is becoming a very dirty one.

One claims that Obama is "certainly a racist" by virtue of belonging to Chicago's Trinity United Church of Christ, which it says "will accept only black parishoners" and espouses a commitment to Africa. Actually, a white theology professor says he's been "welcomed enthusiastically" at the church, as have other non-blacks.

Another e-mail claims that Obama "is a Muslim," attended a "Wahabi" school in Indonesia, took his Senate oath on the Koran, refuses to recite the Pledge of Allegiance and is part of an Islamic plot to take over the U.S. Each of these statements is false.
