Too bad there isn’t a space on the ballot for “I don’t like the incumbent, but the challenger is so much worse I’m voting for the incumbent anyway.” A sort of vote of no confidence vote. With luck the barely passable incumbent would get enough votes over the impossible challenger to stay in office but still get a message that says “I was not only holding my nose when I voted for you, I was looking for my gas mask."
This was prompted by a recent news story that basically said this session of Congress was the least productive of recent history, coupled with what seems to be record number of congressmen leaving under big thunderclouds. I'm sure I'm not the only one looking for the tar and feathers.
I'm not sure what we'd do with the information. Tell 'em they've got one term to either turn it around for the incumbants or get it together for the new guy. If they win with the conditional votes again, they're out and a new election would be held.
