It started off innocently enough as he made small-talk with Minnesota Sen. Amy Klobuchar, mentioning, in passing, that senators often take off their ties when negotiating bills behind closed doors. Klobuchar needled him about it.
Klobuchar: "Ties off?... But I don't wear a tie."
Brownback: "I could say ‘dresses off' but I won't."
Klobuchar (laughing, blushing): "Not while you're running for president."
First, eww. Second, I'm sure the Gannon-Coulter defense, "He didn't actually say she should take her dress off" will be brought up by Brownback's supporters who will refuse to see this as anything for which he should be condemned.
A mountain out of a molehill? Perhaps. But I sure wouldn't be happy about a colleague making a crack like that in front of me.
