I'm not sure but I know that Black Live Matter, Antifia and the resist movement will hurt the democrats in 2018 and 2020
Bigoted voters aren't going to vote for Democrats, no matter the platform. Resistance movement is going to help the party growth in the next three years, with Trump scandals pilling up and having a lack of accomplishments. Republicans are going to have something if they want to continue their hold in Washington.
Normal everyday voters don't like people who beat other people up, cause riots, and kill police officers just cause they don't get their way.
Well then its a good thing the Democratic Party is very unlikely to nominate anyone who supports any of that.
