He hasn't delivered M4A yet. He's just as bad as Trump.
He only one the popular vote by 4m, as others have said 71m of his constituents voted against him. But whatever you think of them, he is still their President. And unlike the orange thunderc*nt, he will try to govern for the whole country, not just those that voted for him. Anyone expecting differently will be disappointed.
It is still turning the Titanic before it's on a path to definitively hit the iceberg, imo. The issues are still there: the divisiveness, institutions enabling minority rule, money-running politics and so forth. But at least the future isn't as clearly written as failure anymore.
For those bitter that the US didn't elect a more progressive candidate, I'd suggest just waiting before you give up, and maybe being appreciative for at least a few days they didn't re-elect Donald Trump.
