The Daily Caller’s Jeff Poor snags video of a blooper by Sen. Mary Landrieu, D-La. during a debate with Sen. John Thune R-S.D. about a border fence.

“A smart fence which is what Sen. McCain and I want to build — since he’s from Arizona, I think he knows more about this than the senator from South Dakota who doesn’t have a border with Mexico, but only Canada and that is quite different,” she said.
