What I’ve read in recent weeks is that people have been donating to the “Biden-Harris campaign”, so Harris has access to all that money by default.
While I would love a stronger candidate (Whitmer, perhaps), I understand that Harris is a lot less complicated. My understanding is that she can just take the money and run (for the presidency).
Edit: Personally, I think (and thought back in 2019/2020) that Biden should have pulled the same move as James K Polk, and declared upfront that he would be a one term president. Then we could have had a competitive Democratic primary, which would have stood out against the Republican coronation.
What national ID?
The US doesn’t have a national ID card. I have a federally-issued ID card as a lawful permanent resident, but the typical US citizen has what? Their main proof of citizenship is their birth certificate, issued by their state, and doesn’t have a photo (and if it did, would probably be a baby photo). The people with passports tend to have enough money to travel internationally, which is a pretty small proportion of the population (as it’s a big country, so even a lot of people who can afford vacations will vacation in the next state over at most).
