I doubt there are many dyed-in-the-wool Republicans as such, but I'll bet there are many who still identify strongly enough with the old-school Republican messaging around rugged individualism and supply-side economics that they view the median Democrat as actively destructive by comparison to the merely flawed median Republican.

I'm far from being one of those myself, but I imagine the argument would be that any regulation one could propose to address this is bound to be worse than the problem itself, in terms of chilling effects on legitimate speech and commercial activity.
