I have no idea how anyone can still be a conservative (under the current definition in America) at this point, but any such person with any synapses still firing will surely realize by the end of this term that:
1. late stage capitalism has fully gone off the rails and sucks ass for people who aren't wealthy, especially when the govt stops doing anything to regulate commerce for the greater gods inadequate billionaire oligarchs set policy and are above the law;
2. our campaign finance system is complete trash, especially when combined with #1 above; and
3. the federal bureaucracy actually did a lot of good things for people and most of the regulation we've developed over the centuries wasn't just wasteful red tape.
Of course, it won't surprise me if few end up having the meager brainpower necessary to realize these things after the next 4 years of hell. But regardless of how many of them do, by then it'll be far too late to unfuck the country, the economy, our relationships with allies and global standing.
