As has been clear for a while, the GOP front-runner is not a conservative. The damage from a Trump presidency would be long-lasting in ways much different than a Hillary presidency. While I believe both would introduce policies which would be disastrous, the Trump effect would chip away at conservatism as a whole.
Hillary vocally stands in opposition to conservatism because she is a liberal. Trump knowingly stands in opposition to conservatism while pretending to wave a banner of allegiance to it.
We can counteract a Hillary effect with its strong opposite. We cannot counteract Trump with a crumbling foundation...
