Anecdotes are not science. She ought to have known better.
I use to like Bachmann, but there is an impulsiveness and/or intensity about her that concerns me re: her judgment. There is something about her that reminds me of Glenn Close in Fatal Attraction (I think it's the eyes).
You go over the line here into sexism. She is a beautiful woman. "Impulsiveness", "intensity"? Santorum has the same, yet you would nevey make such a silly comparision. C'mon.
Howard Dean has the same problem (even Dims thought so), so I don't think it is sexism.
And as to beauty...when it comes to a presidential candidate, beauty is simply not part of the equation.
