Us Dem's have forgotten what the first year of Clinton looked like. Different issues but I wouldn't be surprised if Gallup polls didn't have Clinton and Trump at similar popularity levels. Difference being that his people could get replaced by boring insiders in a way that doesn't seem possible for Trump.
It is amazing that people think Comey's testimony is nothing. Impeachment is primarily a political question so nothing is going to happen as long as Ryan is the congressional majority leader. But it is no longer news reports; the former head of the FBI, who beat an admin before, under oath testified both that the President is a liar and that all the building blocks exist to start a criminal case for obstruction.
