I hope to purge those people and send them back to the Democrats where they belong.
The reality is that the same voters who turned out in huge numbers to toss out Richard Lugar and vote for Richard Mourdock in overwhelming numbers also voted for Romney in overwhelming numbers. It may not make sense but that is what happened. They decided they wanted Romney - not the GOP-e - otherwise Richard Lugar would have also been the victor by far. Same thing happened in Kentucky when voters chose Thomas Massie as the GOP candidate in the 4th Congressional district - the tea party favorite over establishment candidates.
Knock the nonsense off and start doing something constructive - like get Mourdock elected, Deb Fisher elected, etc. Complaining about Romney serves no purpose at this point. If you continue to spend all of your time doing this to in effect help Obama rather than alternatives like that, it will demonstrate you are simply not sincere and are part of the problem you claim to be railing against.
