If you look back on the history of presidential elections, incumbency has significant advantages that only a fool would ignore. Until Donald Trump, it is notable that four out of the last five presidents all won reelection despite facing a myriad of obstacles. Incumbency matters.
But if Joe Biden bucks this trend and loses in November, the primary reason for doing so will be because he is captured by the progressive left. People forget that in the Democratic primary of 2020, Bernie Sanders was on track to clinch the nomination until moderate southern Democrats on Super Tuesday heeded the call of South Carolina’s James Clyburn to support the noticeably more moderate Senator Biden. The rest is history.
