Name one election that Levin or any of the others endorsed a presidential candidate before the primaries.
Then name one time Levin or any of the others did not endorse the eventual nominee.
Mark Levin (up to this point) has endorsed the eventual winner.
Most people here at FR (up to this point) have supported the eventual nominee.
A lot of people here at FR won't support the eventual nominee this time, if the nominee is a RINO.
Donald Trump HAS pledged support the eventual nominee this time.
So since you're so mad at Mark Levin, what does that make Donald Trump?
