I'm talking about all voters, America as a whole, not just those who vote in the Democratic primary. The fact that independents went for Biden big, 54-41 shows he was the right choice to defeat Trump. I doubt any other Democrat could have rang up that large a margin. Biden had the reputation of being a moderate Democrat, a decent guy, a likable guy, someone who could attract the swing voters, something Hillary couldn’t and a few other Democrats in the running. In the context of 2020, Biden was the right guy. In the context of 2021, maybe, maybe not.
The primary goal, maybe the only goal for the Democrats was beating Trump last year. Everything else was secondary. Heck, they’re still bashing the heck out of Trump. Just read some of the post here on this site. You get the impression some still think Trump is president.
Could someone else have beaten Trump, we’ll never know because it never happened. I think some could have, some not. I think one needs to realize when it came to independents, it wasn’t Trump’s policies they were against. They were evenly split on them. They didn’t like Trump obnoxious personality, his childish behavior. I would say they were looking for someone who acted like an adult, a grownup with little baggage. Someone who would bring back normalcy and sanity to the office of the presidency.
Of course, there will be differing opinions, I look on 2020 from a swing voter, a non-partisan point of view and an election forecaster. Others here look at it from a purely, 100% Democratic Party or liberal perspective. That does make a difference.
