At least SNL does a less-than-flattering impersonation of Hillary too. They’ve even poked fun at Obama a few times. I’ll give them credit for that. They could be as one-sided as most network comedy shows.
At least Fey and Hammond's impersonations of Palin and Trump are funny. Kate McKinnon's Hillary Clinton is just terrible. To be fair to McKinnon, in nearly 25 years and I don't know how many cast members, SNL has never been able to field a good impression of Hillary Clinton
