Remember, if you do not vote for someone, it is because you are racist/misogynist/Nazi/etc. It is not because you disagree with them, it is because you are racist/misogynist/Nazi/etc. I am guessing the Dems will want to change the rules in the primary to make sure that you can cast a vote for every candidate, so that you cannot be criticized for anything. If you vote for Booker over Harris, it is because you hate women. If you vote for Warren, it is because you are racist.
