You're asking me how much Dems have to lose in order to understand why they're losing and to stop playing chicken with our democracy?
How would I know that? You would hope one lost election to a reality TV star rapist would be enough to prompt a post-mortem, but the idiots learned nothing from 2016 so I would imagine it might take a while for it to sink into their thick skulls. How long does it take someone to add 2+2?
