I don't see the problem with it. How is this different from Fox, MSNBC, etc?
The guy ran a historic, nation wide, and unusual political campaign. If Mike Huckabee can have a show on Fox I don't understand how this guy merely being a commentator is worse.
Mike Huckabee happened to be a governor for 11 years and won 8 states in the 2008 primaries... not really comparable.
Like I said. Huckabee did nothing historic.
Plenty of senior campaign staffers end up on cable news. MSNBC, for example, loads its roster full of Republican Presidential campaign staffers - Nicolle Wallace, Steve Schmidt, Ben Ginsburg, Rick Tyler, etc. - but all of them are far more "respectable" than Lewandowski, who is plagued with controversy. Even people who didn't like Cruz like Rick Tyler, and even people who didn't like Bush/McCain like Nicolle Wallace. I don't know anyone who actually likes Lewandowski or is interested in what he has to say.
There are plenty of people I don't "like" on cable news who aren't significantly connected to anything historic. "Liking" someone is not my litmus test for who should or should not be on cable news. Honestly if your standard is Huckabee of all people gets a full show I see no reason Lewandowski can't be a commentator for a few months. After Trump goes down in flames this guy isn't going to have a job at CNN.
