You are correct. Levin is a true Patriot, however, he seems incapable of ever leaving the GOP.
He can't seem to face the cold reality that the GOPe dominated party must be politically destroyed.
Destroyed by having millions upon millions of Conservatives leave the evil GOP in mass and start a true 2nd Party.
No, Levin just wants a voice in the 2016 primaries, but the primaries are now dominated by the “moderate” Republicans.
