Has Pence even done anything worthy of criticism since he became VP?
Very likely he lied about his knowledge regarding the Flynn debacle and other associated Russia-related issues where he was a fixture in the scapegoat responses. (I mean unless Pence literally was such a lame-duck he knew absolutely nothing going on. Either way looks bad for him)
He got caught using a private email server that was hacked in his home state of Indiana a few months back. (Like this was kind of unbelievable and drowned out over more stupid hypocritical stuff)
He has a thing against dining with women outside of his wife. Too much sexual tension or something.
Beyond that, he has shown zero willingness to push back on any of these horrendous GOP policies, which isn't unique, but proves the guy is literally nothing but a tool. Not that it is unexpected, but still worthy of as much criticism as any of the others.
