Intuitively, you’d think younger millennials would be more supportive of Obama because his health law allows them to stay on their parents’ plan longer for free. Why is it the opposite? My working theory: older millennials are more supportive of the president is because they were around to vote for him in 2008, and so have a more visceral tie to his policies.

I asked IOP pollster-in-chief John Della Volpe if he thought my theory was plausible. He responded, “Not only is that plausible but I agree!” So it may not be so much that the 18-24 set likes Obama less; they just don’t risk their egos as much by not supporting him.
