Try paying attention to how a president actually governs and how they've affected material conditions. If you look at it that way, Trump is at worst the level of Obama (who started 5 new wars), and several orders of magnitude less bad than W or Bill Clinton. Remember, Lincoln project wants to invade Iran/Vz/Russia. Fuck those war criminals
Hedging bets about harm reduction between two openly Imperialist candidates is pointless.
Trump pretty successfully continued the genocide in Yemen. No one else would even have attempted Iran. No one could say whether anyone else would have succeeded in Venezuela. I'm sure he was involved with the success in Bolivia.
The fact that he seems incompetent isn't actually preventing the damage from being done because he mostly isn't involved. The US's abilities in general are declining, regardless of him.
