In a speech at St. Anselm College in Manchester, N.H., on Tuesday, Rick Perry seemed to mix up the voting and drinking ages -- not to mention the date of the coming election.

Those of you that will be 21 by Nov. 12, I ask for your support and your vote, Perry said. 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. The idea that you're looking at a $15 trillion debt, that you're looking at entitlement programs that will not be there for you if we continue on this path, is not fair to you and it's not right.

The voting age in the United States is 18, and there is no election on Nov. 12. The New Hampshire primary, which is what Perry is campaigning for at this point, will be held on Jan. 10, 2012, and the general election, which will pit the Republican nominee against President Obama, will be Nov. 6.

It was a slip of the tongue, not a substantive gaffe -- nobody really thinks Perry doesn't know the voting age -- but it was one of many YouTube-worthy moments of the Republican primary race.
