12:40pm Eastern update. Vote-switching weasel Sam Brownback should really just end his presidential campaign bid right now and stop wasting his poor staff’s time.
Reader Dave e-mails: “I think an enduring legacy of the vote will be a new nickname for the Senator from Kansas: Ladies and Gentlemen, I give you Senator Sam Switch-back.”
I really like that: Switch-back. Has a nice ring to it. I also like "Brownback McWeasel", but that's not nearly as creative and can be interchangeable with just about any name.
Absolutely perfect.
