Buddy, I'm not content with "better than Republicans". The Republicans are getting worse every year and Democrats are happy to follow closely behind.
Diverting any of the efforts that went into passing the ACA to stuff like codifying roe v wade or staging a big crackdown on wallstreet most likely would have ended up with the ACA getting axed.
You're free to believe that. I believe they intentionally dragged it out specifically so they wouldn't have to deliver anything else. Because most Democrat politicians are pro-corporate trash who are enabling the drift into fascism if not outright facilitating it.
