I had watched a guy say things for 5+ years like "I've got a plan to replace the ACA that is better and cheaper, just wait." And they never materialized.
That was always BS though. Trump wasn't personally developing the vaccine. "Big Pharma" was, and you either trust them or you don't. (And until about ten minutes ago, liberals generally didn't.) Bringing Trump's personal credibility into the issue was done in bad faith and only to gain political advantage going into an election.
Nevertheless, I understand how you feel. I'm still waiting for my health insurance premiums to drop by $2,400 per year.
He pooped it down his leg by not lining his family up and having them get vaccinated in the most public way to praise the "trump" vaccine. He was too busy losing the Senate for the GOP. They should have put a .22 bullet behind his ear on the 1/6 impeachment and they'd have washed him out of the system and marginalized his ilk. They didn't and he's leading the party.
As you know, I would have impeached him too. My big objection is to the sanctimony and historical revision. Your side politicized the vaccine and undermined it until it wasn't politically advantageous to do so (meaning after the election). If Trump had won, I think Democrats would be far more sceptical of the vaccine than they are.
