They could always have used the "nuclear option" and passed actual universal healthcare instead of our strange hybrid for-profit insurance monster under Obama, but they didn't want to.

When Biden was the President, Ds had majority in house and senate (117th). They COULD have used the stupidly named "nuclear option" and passed universal healthcare, higher minimum wages, and more in response to the nightmarish Trump presidency

But... nah

(encourage everyone to check out the super-majority fiasco fillibuster-not-really nuclear option bullshit song and dance)
