I still find it incredible that out of 330 million people, these two presidential candidates are the best America can do.
But it's not out of 330 million people.
The US President has to be over 35, which eliminates half of the population. The President also has to be a Natural Born Citizen; That lowers the pool still further.
Most importantly, nobody can be a serious candidate for the presidency unless they have been politically active for most of their adult life; or are famous; or are wealthy; or ideally all three. ...It takes a long time to become 'presidential material' in the eyes of the two major parties -
That last bit was true for both parties up until 2016. Yet the rise of Trump was not an isolated phenomenon. It is the culmination of a decades long process that was marked by Reagan's inaugural "government is not the solution to your problems, government IS the problem" speech.
Biden is not particularly exciting as a candidate. He gaffes, grins, gives inappropriate shoulder massages, but for his entire life has been a public servant. That last part is bad according to the modern GOP. Government itself is bad, and anyone (except their own long-serving political animals, of course) who dedicates their life to a career in government is therefore wholly incapable of running that which must be destroyed at all costs...before it's soaked for all the money possible.
Trump's qualifications are not that he's allegedly rich and famous, but that he's the pinnacle of Republican ideals as of late. A grifter who will accomplish their goal of making a representative government useless while private industry finally seizes the last remaining levers of power. Is it going to be ugly? Sure, but in order to make an omelette you've sometimes got to destroy a republic.
It wasn't always this way. The first President I remember was Nixon, and for all his many faults, he was at his core a public servant. A patriot, even. His misdeeds were premised on an ends justify the means philosophy, but the end was to make the country better. Trump's end is utterly self-serving. He couldn't give a fuck about the country except as it serves him, and that has become the qualification that makes him worthy of the Presidency in the eyes of modern Republicans. He is the means to their end, and has performed spectacularly. The state department is gutted. The justice department is hopelessly corrupted. Most of his cabinet secretaries are people explicitly hired to destroy the agencies which they head.
Is Biden the best the Democrats could do? Not by a long shot. Yet I have to believe that at his core, "Sleepy Joe" is a dedicated public servant who feels his policies are what's best for the country, and not necessarily himself. Is he a creature of Washington? Yep. Is he an insider? Yep. Is he the presumptive nominee because he's just outlasted and outmaneuvered everyone else? Sure. Yet at the end of the day, he's actually qualified to do the job he's applying for. If elected, he will do at best a passable job. Trump? His party embraces the fact that he's wholly unqualified. That's precisely why they like him so much.
