Mondale, Dukkakis, Gore, Kerry, and Hillary Clinton were all considered to be the ‘safe’, ‘moderate’ choice and all lost their elections. The only two Democrats who’ve actually won a presidential race were considered the unsafe choice; there was certainly a lot of talk from non-Obama fans about how risky of a candidate he was (first black president, after all), and Bill Clinton got the nomination basically because none of the big names wanted to go up an incumbent with bold military victory in his record (Bush Sr looked hard to beat). So why do people talk as though running a fairly bland, safe, establishment-friendly candidate is likely to win an election for the Democrats? It failed miserably in 2016, and also in 2004, 2000, 1988, and 1980, but people on here seem to insist that ‘electability’ in the form of being pretty middle of the road and liked by ‘traditional backers’ is the key to victory.
There doesn’t seem to be any actual data supporting the claim that Biden is highly electable. Putting aside his personal flaws and vulnerabilities (‘Hunter Biden’ is a name I expect to hear any time Trump’s corruption is mentioned), it seems like he’s the kind of safe Democrat that loses elections. What victories am I overlooking, or what other data is there?
