Translation:
“He pissed off liberals, so I had to sign off on whatever it was.”

You know, eventually one of these yokels is going to rubberstamp something that’s beyond the pale even for them, just because it pisses off liberals. Some big name national level Republican is going to give the thumbs-up to something truly awful just because the person who said it got an angry segment from Lawrence O’Donnell.
It should be fun to see the back-tracking then.
