Why can't the GOP get this right?

Remember North Carolina GOP Congresswoman Virginia Foxx, who said in April that it was a hoax that Matthew Shepard's murder was motivated by his sexual orientation?

She let a bit more of her brilliance shine this week on the House floor (topic not noted) when she stumbled over an adage (flubbed famously as well by George W. Bush), saying, "Fool me once, shame on you. Fool me twice, shame on you."

I will give her some points for her skilled use of the pen for emphasis.
