Presidents are very limited in what they can do by design. Most presidential campaign promises rely on the planets to align (i.e.: Congress to actually do it's job and legislate, which it often doesn't). Presidential failure is misnomer, imo, because it's Congress who writes the laws. Biden's executive orders can be overturned as easily as he overturned Trump's. At best, the president provides a vision on where he thinks the party should go but Congress does the heavy lifting.
And if he fails, not only do we not get the progressive promises, but the other president takes more away.
That's how conservatives think too about their president: if he fails, not only do they not get to roll back the administrative state, but then a progressive can tax the more to put more criminals on the street.
The misconception is that this must be a bad thing. What makes it bad is that Republicans are bat shit insane and want control of everything. But if their views were not moderate and they believed in democracy, then it wouldn't be so bad. Still disappointing though.
