Maybe folks up north don’t understand it, but the tailgating ritual at LSU is bipartisan if also boozy. We don’t apologize for that, even if it’s a little much for some.

We say that because of the latest small flap in the U.S. Senate race, in which no less of a personage than U.S. Sen. Mary Landrieu briefly manned the tap for a 20-something LSU graduate doing a keg stand.

And if you don’t know what that is, we congratulate you. But it’s part of tailgating, and so we agree with Landrieu’s response to critics of the photo, which went out nationwide.

“It’s just the way we roll,” Landrieu said. “The gentleman that did that is 28 years old and he has also graduated. He has a master’s in business. So I think he can make a decision for himself what he’d like to do.

“I thought I did pretty well by not doing it myself and just helping him,” Landrieu said with a laugh.

For what it’s worth, the LSU-Mississippi State game tailgating was the scene of two LSU graduates campaigning, Landrieu and U.S. Rep. Bill Cassidy, of Baton Rouge, her leading GOP opponent in the Nov. 4 primary.

One element of Cassidy’s campaign is to assert that Landrieu’s long service in Washington, where she and her husband have raised two children, means she is out of touch with Louisiana. A hard argument to make, post-keg-stand.

Politics is about symbols, and only in Louisiana could a keg stand have political significance.
