I think the fact that he deleted almost all of his past tweets because they came under fire...including one that stated that the Nazis had some good ideas, is a solid example. He often strips things from MMFA and Think Progress (which he used to writer for!) without fact checking them at all. He helped perpetuate the idea that cross hairs on a map caused violence. When Obama was in office he falsely lowered the national debt by trillions of dollars to make things not sound so bad. So, so many examples. Don't even get me started on the "Voxsplainers."

On Twitter he is basically considered a joke on both sides of the aisle.
