Yeah, I think you might be right... I do suspect that Trump is specifically tapping into a pro-crypto stance to secure the Libertarian vote away from Chase Oliver (and possibly because he's trying to drum up more money and so is accepting crypto donations now). Trump was against crypto when he was in Government, but now that he's personally benefitted from it he's changed his mind... which tracks.
I don't at all think that all Democrats oppose crypto, especially since H.R. 4763 had bipartisan support, 4 Democrat co-sponsors and passed the House of Representatives (approvals not along party lines) and probably would have passed in the Senate too... but yes, I completely agree that for single-issue crypto voters the GOP is clearly leading.
I don't actually know if Trump/GOP/Project 2025 has any policy outlined regarding crypto though. Be interesting if anything is promised during the Bitcoin convention.
