Biden is extremist by the standards of progressives in that he’s basically not progressive. He’s not a moderate Democrat, he’s far right of the DNC, which puts him ever so slightly to the left of the GOP. The only viable candidate for the DNC given FPTP was either going to be far right or far left, and with the push by their core to make sure Bernie was out of the running far right it was.
Biden is not far right of the DNC, that’s an asinine claim. If anything he’s towards the left of the DNC. The DNC is just right-center as a whole. (There are obvious exceptions in true progressives that are under the Dem banner because of fptp, but there are like 10 of them or something).
I think the confusion in this case is also a symptom of the problem. On the one hand you have the voters and on the other hand you have the politicians. By the standards of DNC voters, Biden is far right. His platform was basically undo Trump then don’t change anything after that. That’s not progressive and it’s not what DNC voters really wanted, but it was the best option they were given.
On the other hand you have DNC politicians. By their standards Biden might be center of the pack, but only because most of them are clumped up over on the far right. There are very few actual moderate Democrats these days. There are a handful of extremists out on the far left like Bernie, a few moderates in the middle, in then the vast majority over on the far right that a couple decades ago would have been considered Republicans.
Democrat voters haven’t really changed, but the politicians have shifted right as Republicans have moved ever further right. That’s why Democrat voters are unhappy with Biden, they’re looking for a moderate candidate, not as extreme as Bernie, but looking to make actual reforms. That’s why they loved Obama, he talked a big game on the campaign trail, and once in office was really good at spinning most of his compromises as wins (just look at Obamacare, literally a Republican healthcare plan that was somehow spun as the socialized healthcare Democrats had been pushing for).
Words have meaning. Far right is literally fascists and Nazis. Are you saying that Biden is a fascist?
Biden is not closer to the GOP than the DNC. Either you are idolizing the GOP in thinking Biden could represent their platform, or you misunderstand that the DNC is not so far left from Bidens platform. Bernie is literally a different party but ran on the democratic platform for the elections, but the DNC itself identifies with Biden and Clinton politics.
