Biden is old, he doesn't speak well, and did I mention he's old. But he's a savvy lifelong career politician. An old savvy one. He's still around because he's been getting things done for a long time. And bipartisan things, no less.
His 'competition' for office is also old. An old dumpy guy with zero savvy and was never able to hold any sway with Mexico or any other country. Just endless arguing with no progress. Old, but zero political experience, with no actual record of making a dent in anything. Literally not a single piece of significant progress - none.
Old dumpy guy spent his time arguing, followed by angry twitter posts, then focusing on his personal profit, and then more arguing. Then blaming the opposing party for everything he hasn't been able to do or did wrong. Self-praise for basically being perfect. Then all over again, on loop.
That was a messed-up loop I hope I don't ever have to see again.
