Krugman lays out the trajectory:
Here’s how it ends:
...So when I say that I miss voodoo economics, what I really mean is that I miss the illusion — which I shared — that the impact of its rise would mainly be limited to the politics of taxes and spending. What we now know is that the embrace of crank economics presaged the general moral collapse of the Republican establishment.
This collapse opened the door for paranoia and conspiracy theorists of all kinds — and the consequences have been deadly. There is, I would argue, a direct line from the Laffer curve, to Jan. 6, to Buffalo.

Read The Whole Thing — the link should get through the Times Pay Wall.
Krugman has been calling out the GOP for years now, one of the few voices at the Times to do so consistently.
