Oh c'mon now OP. You’re talking gaffes? Trump looked at the sun during an eclipse. That should “trump” about everything, but if not enough for you he thought injecting bleach would work, said windmills cause cancer, said his dad was born in Germany (he wasn’t), implied Frederick Douglas is still alive, claimed you need a photo ID to buy groceries, praised Washington's Continental Army for taking over airports during the Revolutionary War, during a speech to thousands of Boy Scouts talked about rich people having sex on boats, told a hurricane victim who had a boat land in his yard, "At least you got a nice boat out of the deal", told reporters that his Covid test came back "positively toward the negative", said Andrew Jackson could have stopped the Civil War (Jackson died long before the start of that war), referred to neo-Nazis and white supremacists as fine people.
And don’t forget, he tried to overturn a freaking election. Did nothing for hours as rioters beat up, tazed, pepper-sprayed cops, resulting in over 100 being hurt. FFS if this doesn’t eliminate him from candidates you consider, you have a serious problem.
