* "Trickle Down Economics": Large tax cuts for the wealthy while simultaneously dismantling social programs which benefit everyone else
* Arming authoritarian and far right militia in South America
* Environmental deregulation
* Giving a voice to the religious right and their anti-gay/anti-woman agenda
Also: regulating ketchup as a "vegetable serving" (so school lunches didn't need to have fresh veggies).
Just thinking outside the box on how to completely F up government to serve their agenda.
Expanded from bullets (e.g. Iran-Contra) there was badness, but what would be helpful would be to:
1) Expand those out a little bit, to where we can see the bad.
2) Compare to other presidents for level of bad.
On the whole, I have complex feelings here. The quality of recent presidents and presidential candidates has been very, very low. I think I'd take Reagan over Hillary Clinton, Trump, or Biden. On the other hand, I think I'd take Obama, Romney, and probably McCain over Reagan.
We see an entire portion government apparatus effectively obsessed with killing the government, but only performatively. This is what I see as a Reagan special.
FWIW, as much as a president has a soapbox to advocate from, budget and tax policy are set by congress.
