Well, in my experience, people are very polarized about this: either they want to go to the gulch, or they want a very protective state that deals with everything. Both population seems comparable, number-wise; YMMV.
Personally I can't help but reading anyone trying to blame underregulation on libertarians as effectively an admission that they have run out of excuses. There just aren't enough libertarians to have that much of an effect on anything. Even "deregulation" is not generally the libertarians running wild, it's non-libertarians trying to implement a "free market", for some definition of said, but they're generally not libertarians and the same people will happily vote for crony capitalism or a ton of other sorts of regulations.
