You’re just now noticing?

It’s not only weaponized - it’s also that polling methodologies are still largely focused on random cold-calls from unknown numbers, which basically nobody under 40 picks up for because we don’t have land lines, and have moreover been inundated by spam calls and texts CONSTANTLY for quite a while now. Any polls run under that methodology will absolutely have a very strong demographic skew towards older people as a result. Thus, the data becomes increasingly inaccurate as you restrict to respondents younger than about the Gen X midpoint.

Polls are like “science journals.” You only want to pay attention to the reputable ones.
