Adoption can happen without necessarily an "candidate" supporting bitcoin directly per se. As long as there are not overwhelming negative legislation that is put in place that completely restricts access, I think that there is enough organic adoption from grassroot individuals to fuel network growth anyways.
Commenting on the candidate's idea of basic universal income: sounds interesting, if not immediately viable, but the models haven't been put into proper practice. It will hit home with many voters, but none who understand the crisis the US economy is already in. Even with crypto, I think I've come across a couple already attempting the concept but its got to be entrenched in some centralised aspect to kick off, so that will go down well in my opinion.
Exactly, you have to look at all sides of what they are advocating for. Not just with crypto policy.
Also, you have to look at how legitimate of a chance they've got to actually succeeding.
