"Conservatism" ought to spend a lot of energy, resources, money on reselling conservatism, itself.
Just mocking the democrats' candidates gains little, and the resouces spent doing so, could better be deployed.
However "conservatism" has been in the doldrums for so long, few seem able to resell it to voters.
In effect people are asked to listen to "democrats are so bad, and we are not them" and base their choice on that alone.
All over the modern developed world, there are left, center, and right parties. Australia, Canada, Sweden, etc. There have been for over 100 years.
I think Reagan, Friedman, Laffer, Jack Kemp talked more convincingly than people today.
It is a collective criticism.
