Here's the deal with Biden - he ran in a field that really didn't have much. If there was a bill clinton type of candidate, the election would've been a blowout.
There was nothing from the republican side other than a trump who couldn't dig his own hole deeper fast enough, and if you told him the hole was getting deep, he'd dig faster to show you how big of a baby he is.
On the democratic side, you had a somewhat odd socialist takeover attempt from progressives that never gathered steam. Everyone wanted a mild candidate, and they got that with Biden, but they were running away from something (Trump) and not toward something. Why did trump get elected? because Hillary and most of the democratic and most of the republican establishment were getting way into the globalist economic thing and the public here was getting tired of it. Half of the country can't stand Hillary, and even in that case, the alternative was (incompetent) Bernie. Biden rises to the top and the lukewarm desire to have him elected was displayed in the fact that he barely beat a terrible sitting president. Terrible as in the worst I've seen in my lifetime.
So, we got the presidential version of white bread with no salt. It really bothers a lot of people that Biden is actually moderate, at least reasonably so.
I don't have great hopes for the next election - people are voting against candidates rather than for. Maybe an even worse outcome would be another very charismatic candidate who really only has their own desires in mind - ego.
If we look around the world at leaders, though, let's be honest. Do we want a Xi type instead? A strong leader propagandized and kept in by ideological force? No. Putin? No. Johnson? No. Bolsonaro - no. Trudeau? No.
I like Merkel, but you don't find many of those. Maybe it's a statement of the practicality and sensibility of the Germans to have a Merkel and the rest of us have the above.
