They actually believe they're winning voters with this hate Trump game. Just like they thought the 2016 election was an absolute stone cold lock, just like they actually believe Trump committed some sort of impeachable offense.
There's a missing gene, evidently a very important one too.
The only people they're impressing are their far left base that already votes for them by extreme margins. They don't know that winning NYC & LA & Chicago & DC & Philly & Detroit by larger margins will NOT gain them any more power.
Not only do Trump voters still support him, I believe people of reasonable minds are going to see through this bullshit, realize the economy really is on an uptick and vote against the poppycock, the lies and the hate.
