At this point I doubt I'd support Michele Bachmann for the presidency, but retailing the idea that she doesn't know the difference between John Wayne and John Wayne Gacy is ridiculous.
Just so we're clear on this -- Gacy apparently was from Waterloo, Iowa. John Wayne's parents lived in Waterloo, Iowa prior to Wayne's birth. It's not surprising that someone might have claimed John Wayne as a son of Waterloo at some point.
And just so we're clear on one other thing -- John Wayne became famous elsewhere, just as John Wayne Gacy became infamous elsewhere.
The campaign that is beginning way too soon is designed to determine should be the President of the United States, not who has the best chance of being the next champion on "Jeopardy!"
