Americans like decisiveness in presidential candidates. While I’m sure we’d all claim to admire and respect Biden’s decision to consult his family in the wake of his son’s death, decisiveness is what’s needed.
There are a lot of reasons why Biden hasn’t been a great candidate in the past and unlike Hillary he has to run largely on the Obama administration’s record, where Hillary, at least implicitly, gets some 90s nostalgia. Many of these can be overcome, but waffling on a decision to run can’t.
This is a critical election. Perhaps not as critical as 2008, but still more critical than most. The balance of power on the Supreme Court for a generation is at stake. If Biden was the best candidate for the Dems if he was in last summer, he won’t be the best if he doesn’t get ASAP.
