The blockchain records and validates every transaction so it is traceable. Your anonymity comes down to what kind of wallet you're using.

As someone else mentioned, these cryptobros are supporting Cheeto Dick Don out of greed.
He's interested in it bc he thinks he'll get away with receiving illegal contributions. The FEC and IRS will be able to track those payments if they ever decide to get involved.
