They are but I think what you are seeing isn't a left v right polarisation in the traditional sense and to characterise it as such downplays what is really happening. For about a hundred years (and prior to this it was our direction of travel) our arguments around how left or right our governments should be, have taken place in the context of what we often abbreviate to Western Liberal Democracy.
This is a different situation, what is currently happening in the US isn't just a different flavour of traditional politics, it's a direct assault on the system that has been in operation for at least century. Its the difference between people who still consider that liberal democracy, warts and all, is still a better way to govern ourselves vs people who are seeking to install (or happy to be living under) authoritarian governments for whom democracy is an impediment to them imposing their will, be that theocratic or economic.
if you read some of the writings of the silicon valley great and the good, it's clear that they see themselves as more capable and able to run the world than our current models of government; and they're not even the worst of the unholy alliance of would be dictators.
