I can see them trending more toward libertarianism, but in order to be conservative, you have to have something to conserve. The Left has done a good job at erasing the values that are worth conserving, so the millennial generation is adrift. All that is necessary now is for their heads to be filled with a potpourri of liberal hogwash and you'll have the first generation of socialist rulers (if we don't already).
The only thing that will restore the Republic at that point is revolution. And there's no guarantee we'll win.
