Personally, the majority of the anti-vaxxers I know are on the liberal side of the spectrum, but that’s largely who I associate with, so no surprise there. The liberal anti-vaxxers are the ones that tend (generalities of course) to feel that GMO / Non-organic / Processed materials are automatically bad for you, and object on the grounds of safety.
The few anti-vaxxers I know (at least by remove, such as at work) of the conservative sort, hate vaccinations because ‘the government’ requires them. It’s a patriotic duty to reject them, plus assorted conspiracy theories normally involving embedded tracking chips and the like.
Both groups are wary, and I’m not even including the people like myself who are pro-vaccine but worried about potentially over-rushed production with insufficiently large test groups. As a (just) sub-50 with no underlying health conditions, I am of multiple minds about getting it ASAP once it become available widely, or waiting although I’d say I’d be 80/20 for/against getting it ASAP.
About how Trump is going to use the vaccine politically, I’m going to bet hard on taking 100% of the credit for getting it out there, and then slamming Biden for the problem not being fixed the moment Biden takes office. After all, in the Trumpy world, he "gave* everyone the fix, and if the US is still having problems with COVID 6 months from now, well, who else could be responsible?

And despite how Trump decided to lowball orders of vaccine, of course any shortages will be Biden’s fault as well. So Trump will treat it as win-win. Meanwhile his supporters will likely under-vaccinate due to the reasons I posted above, as well as general COVID denial, and they will be instrumental in keeping the numbers of transmissions, hospitalizations, and deaths at terrifying highs even with the vaccine.
So, yeah, on this, figure it’s going to be 2020 still for a long, loooong time.
