This is all political. When Trump says he is pro-crypto, it doesnt really mean he is for it. And when Biden is not so pro-crypto at some points, it doesnt mean he is against it. Remember that the US has some giant crypto exchanges, a lot of crypto users, crypto taxes, etc., none of the candidates are against crypto because of that, and/or are really pro-crypto because they need to prioritize the dollar too. They are all the same, promising this and that just for their own interests.
Dont be fooled by political words and never make their promises for the crypto world your decision to vote for them. Vote based on your conscience.
Taking into account the ease at which politicians can lie, it is way more reasonable to assume that everything they say is not true and not change this stance until they have taken steps to demonstrate with their actions they were not lying, and even if it is obvious this is a maneuver to gain votes, this also sends an important message, that this market is so influential on the US and the topic itself is considered to be that important, that now political parties must at least lie about it to try to gain an election, which makes me think that at some point on the near future a US president could at least take some steps towards this market, so they can keep the support of those voters during the upcoming elections.
