Barack Obama and Joe Biden teamed up again this week.

Presumptive Democratic Party presidential nominee Joe Biden has had a big start to his week. On Monday, Senator Bernie Sanders endorsed Biden’s candidacy, just five days after ending (the modern parlance is “suspending”) his own presidential campaign. Sanders, whom we have criticized in the past, deserves kudos for ending his campaign and endorsing Biden before the Democratic National Convention, if any, takes place. In 2016, even though Sanders was similarly all but eliminated from a mathematical standpoint by Hillary Clinton at this point, he kept his campaign going through the convention, which led to a lot of ugliness and divisive attacks that arguably hurt Clinton in the general election against Donald Trump. This time around, although Sanders regrettably is asking supporters still to vote for him in the remaining primaries so that he can amass more delegates and possibly gain more liberal concessions from Biden, at least Democratic voters, office holders, and other officials can now make the shift toward the general election campaign against Trump.
