When did Pelosi explicitly say she didn't support universal healthcare? In her words, not in the videos that you like to post that provide you thought guides, she explicitly said she supported universal healthcare. If you are referring to her saying she wasn't supporting the introduction of a bill next year, then I refer you to your own words about a Republican held congress. By the way, Clinton isn't a private citizen and her beliefs are not important. I'm not up on what Feinstein said, so without argument, I'll just cede your point. What those two women who are public officials say is pretty much swamped by a movement in both houses. A majority of house Democrats have signed onto a bill sponsored by Dem John Conyers that would expand Medicare for all in all 50 states. Sanders is working on a version for the Senate, there is nothing to hang a hat onto, but I think it will receive good support.
Believe what you want but what you are saying is patently false.
In your own narrative, it doesn't matter to you what Democrats do. You still bash them. In 2014, when Democrats held a majority in the Senate, they in fact did support the repeal of CU. That is in the Congressional record and not subject to debate. A filibuster by Republicans defeated the measure. By villifying Democrats for entering the measure and being stopped by the opposition, you are trying to have it both ways. If any Democrats HAD voted against the measure, you'd be all over it as proof of BAD Democrats and I'd agree. That every democratic caucus Senator supported the measure and still failed, you claim the same. Simply weak thinking.
