This one is short and sweet. With the exception of funding baby bonds, I can’t see any meaningful difference in the real world between a Booker and a Biden administration. Both of them have a reasonable claim to be Obama’s true heir, both of them would try to improve the political climate with mixed success, both of them pass the Putin’s dog test, and both of them are establishment figures and realos.
For what it’s worth, both of them are acceptable to me. Whether the Democratic Party as a whole agrees with that remains to be seen.
