Theory: Trump support is high. After the election, dems will need impeachment as a plausable reason for how they "won" in 2020 (when the real reason will be election fraud). They're not worried about winning - they know their fraud system works. They tested it in 2018 and won the house. They know they can rig the 2020 election as well. But with Trump's support so high, how could they explain winning? The turnout for Trump events is MASSIVE, whereas the turnout for dem events looks like Tuesday night at a karaoke bar in Hooterville. To make the wins look at least somewhat legit, they must fake the polls and try to drive Trump's numbers down with the impeachment debacle.
