But what does he talk about though? There have always been super political things, certainly, but the scope of what was political vs common sense has had a huge shift.

There are polls, in the US at least, asking the same exact questions gong back I believe half a century or more. It is very clear from these polls that this is the most poltically polarized time in politics in decades.

It's not just recency bias - things are really screwed up.

Why (my opinion) one side started caring more about winning than any of their own positions. That then devolved into only caring if the other side loses regardless of what the policy is.

If a party's main focus is the other side loses rather than to successfully govern - you end up here. And the fact they more or less admit it, and people jump to justify it shows how far things have fallen.

Things have always been politicized heavily... But that doesn't mean that things aren't significantly worse than the recent past.

We actually had a political landscape from the 30's to the early 90's that was much less polarized than the rest of our history. We're returning back to where we were in the 1800's.
