Sorry, we can’t tell you that.

Senator Landrieu thinks South Dakota borders Canada. Why does she think it's called "SOUTH" Dakota? http://t.co/UpYP3XlwPF #lasen — Brad Dayspring (@BDayspring) June 13, 2013

It gets better. Landrieu then said this:

Pretty crazy: Sen. Mary Landrieu calls border security amendment by Sen. John Thune a "dumb fence." Umm. — Ellen L. Carmichael (@ellencarmichael) June 13, 2013

We’re guessing even the fence is smart enough to know that South Dakota doesn’t border Canada.

Twitter users were quick to offer a geography lesson and a health dose of mockery:

Sen. Mary Landrieu, call your office….for a geography lesson. http://t.co/e924QuFaIy .@TheFix — The Mad Hessian (@TheMadHessian) June 13, 2013

Senator Landrieu thinks South Dakota borders Canada. Then call fence at southern border "dumb." Pot calling kettle black. #tcot #ctot — PJ Jarrett (@PJJarrett) June 13, 2013

Wonder what the IQ of the Senate is—Sen. Landrieu Says S. Dakota Borders Canada http://t.co/KvL779snoU via @BreitbartNews — Harold J.L. Connett (@HaroldJLConnett) June 13, 2013

Another false statement by a Democrat. Mary Landrieu just said South Dakota shares a border w Canada. #NoItDoesnt — Matthew Boyle (@mboyle1) June 13, 2013

We’re now expecting Landrieu to propose a multitrillion-dollar stimulus project to make North and South Dakota change places, which would create millions of jobs while making her statement correct in the congressional record.
