Perhaps I can recall data at a later point, but from my experience there is almost no presence of mainstream Boomer conservatism among those under 30. You are either far-left, left, center-left, or far right. The center-right has basically disappeared as there is no “woke conservatism”, I do forsee such a movement arising during the “Crisis of the 2020s”.
From an enormous R-I survey (N = 330,063), percentages by age range who consider themselves “very” conservative or liberal as opposed to “moderately” or “lean” conservative or liberal:
Since I ran the numbers I may as well share them, but there’s not much to see here. Those under 40 are only marginally more “extreme” than those over 40. The idea put forward by Feryl that boomer extremism is overshadowing millennial moderate pragmatism doesn’t find any support here though the method is admittedly suboptimal.
The distribution in political orientation among those under the age of 30 (N = 70,305):
Not much evidence of the hoped for collapse of the squishy right here, either.
