Democrats may hate Trump but that's just secondary. What democrats must do is eliminate all those who voted for Trump. Leave the voters alive and they could easily vote for another Trump. The fault is with voting. Without a vote that can be easily controlled there is no security for democrats.
IMO there is absolutely NO HOPE for any voter that would vote for someone with
*NO political experience
*a known 'con man' that screwed many Americans (contractors, students) out of money
*a failed business man that filed MULTIPLE bankruptcies
*a business man that could NOT retain financing via credible institutions BUT obtained loans from Russian sources for DECADES
*a known serial liar
*I could go on but this is exhausting
Yes; you are correct. The voters FAILED to vet the candidate. Nothing will cure stupid.
