I too have been conflicted at times in the back and forth he has done. Some of it valid other times though like you I question the motive. He states it is for principles of conservatism and pulling him on message and back to the right. To some extent I agree. Both sides have their motives . Trump fighting like a junk yard dog where there are no rules and Levin for what remains of conservatism. This has been one very intriguing campaign to say the least
I have been a Levin Fan for years but he has just went nuts over Cruz whom I contend in no way is an NBC. Levin like many Freepers just decided to overlook that whole issue because Cruz said a few good things, of corse Cristy was once revered for saying a few good things as well.
Once you accept that there is no party on our side your decision should be easy because Hillary would be the absolute end of anything that resembles a Constitutional Republic. Sure thing or Gamble what is hard about that decision?
I am probably somewhat older than you and remember a time when I was free, poor but free. Free is better.
