Good example!
The one I think about is Boehner. As long as it looked liked the Repubs would still have a majority in the House, I'd vote for the Democrat if I lived in Boehner's district, simply to get him out of the Speakership. But if looked like the Dems could take the House, then I'd vote for Boehner.
Same goes for Mitch McConnell.
Agree with all of that.
