I don't get what you're hinting at here. The org Vitalik actually links to here that rates politicians on being friendly to crypto, rates individual politicians, not parties, and it claims to have over 1,000 politicians in its database. When I filter for only the ones unfriendly, it lists 49 people. If this rating system is correct, it seems crypto is very likely to be safe based on simply keeping the current people in office in office. It certainly stands out that there are far more democrats than republicans in the against category, but it's a tiny minority of the overall party in both cases.
