Rick Perry has had so many gaffes, it’s hard to keep track of them all. Remember the time he falsely said Texas public schools teach both science and creationism? How about the time Perry said the Revolutionary War was in the 16th century?

Today in New Hampshire, though, the former Republican frontrunner gave us another gem.

“Those of you that will be 21 by November the 12th, I ask for your support and your vote. Those of you who won’t be, just work hard, because you are going to inherit this and you’re counting on us to get this right.”

First, the election is Nov. 6, 2012, not Nov. 12. The election is always the first Tuesday of an election year, making it impossible for the race to ever be on Nov. 12.

Second, as Perry should probably know, the voting age in the United States is 18, not 21.

The Texas governor has already developed a reputation as a candidate who struggles with the basics. This will not help.
