I could be wrong, but the last I checked Trump actually said Bitcoin "seemed to be a scam" and I do not remember any democrat politician being pro-Bitcoin or blockchain in general. Only some hard republicans talk good about Bitcoin, mostly because it's decentralized nature and because the political left can't controlled it.
Ted Cruz is a good example of a pro Bitcoin Republican.
People can change their minds as well.
For example, Michael Saylor used to think negatively about Bitcoin years ago, and now he has completely changed his mind.
At the end of the day, what individuals do doesn't matter too much, the Bitcoin network is already too big.
