I’m not sure the voting demographics support that assertion. More like in a few elections boomers will got overturned. And the backlash is always severe.
I think you deleted your comment. But I don’t think it’s weird at all. If what you say is true than it makes the impact of the choice gap between older and younger voters even more important. Clearly younger voters had to come out in massive force and extremely aligned to overcome the huge conservative bias of their older voting group peers in those elections.
