While I agree that Biden no longer really seems fit to be president, the dangerous Trump argument is absolutely not one to be downplayed. A man that attempted to overthrow the government in a tantrum when he didn't get his way should be absolutely nowhere near close to becoming president again. A sack of potatoes or Biden's literal decomposing corpse would be a better president.
I agree that it's disappointing that these are our only two options and that the Dems could not figure out a better candidate this go around.
