I'd vote for that and I'm a freaking Dem.
What's the alternative? A third party................
The alternative is to organize a third party of dissafected conservatives who will target only RINOS. Think about it. Run conservative candidates against the likes of McCain, Snowe, Collins, in their home states, in both primaries and general elections. DO NOT run a candidate against GOP presidential candidate unless he/she is to far to left. Who cares if Dems win seats? The RINOS never vote with us on the most important issues anyway.
Think it out, no incumbent RINO or wannabe would want to be ousted or defeated if they had conservative opposition on the ballot. In fact, we would be able to exercise more leverage than ever. We have been courted, then marginalized for too many years.
Bring the best and brightest on to the cause. Target our money where timidity dwells. It could work.
