The political divide is because the institutions of power are winning.

It will be and always has been the goal of those with power to deflect attacks directed at them, usually to other groups who are attacking them. For all of his faults, Biden has been extremely good at convincing the lefties that "well, we'd be back to normal now if those damn Republicans would just get vaccinated", effectively turning the normal folks on the left against the normal folks on the right instead of where the anger should be directed: toward the institutions that let millions of folks go homeless, financially and medically insecure, etc. in the face of the pandemic.

The Republicans in power are, I think, a little better at playing this game: they whip their base into a furor over the group in power but only in such a way as they (those already with power) still come out on top. The people are angry at the right group, but for the wrong reasons (and really just to further the agenda of the _worst_ people).
