Trump provided neither.

Security? He threatened to leave NATO. He abandoned our role in SE Asia / Pacific, which China was more than happy to fill. He alienated our allies, making the world a lot less safe. He can't even be credited with border security because the coronavirus took care of that for him (allowed him to enact Title 42).

He literally did nothing for four years, except spread COVID misinformation (and other misinformation) and embolden Russia and China to stretch out their tentacles.

Prosperity is trickier since we can't really blame him for the economic paralysis associated with COVID. However, he did add trillions to the national debt with his tax cut for rich people. Which wasn't good. (I thought you were a budget hawk.)

Oh...and, if elected, he's promising more tax cuts. As if the deficit wasn't exploded enough already.
