Joe Biden had a simple plan. To win the Democratic presidential nomination, he wouldn’t have to worry about competition from candidates to his left because he doesn’t share their radicalism, and the candidates on his right were irrelevant and he didn't want to bother with them. All he had to do was stay in his moderate-to-liberal lane. It’s where he’s ideologically comfortable and where he’s situated himself since he was elected to the Senate in 1972 from Delaware at the age of 29. It’s where elections are won.
