What matters for the election is that RFK, Jr. is talking about that stuff — under the rubric of “Make America Healthy Again” — and the Health Moms are listening, and now he’s endorsed Trump.  This election is likely to be close.  And close elections are decided at the margins.

The Trump Campaign thinks it will get in the neighborhood of 25% of RFK’s voters; other experts think it may be more like half,  with a lot of the remaining Kennedy voters staying home rather than supporting Kamala.  I follow the RFK supporter page for my state and people there seem to be switching over in significant numbers and/or saying they won’t be voting for Harris.

I haven’t seen any public polling that has drilled down deep enough to isolate the Health Mom vote, but I’m sure the campaigns’ finer-grained internal polls will do so.  I don’t know what they’re showing, but I’d be willing to bet that it will be something significant.
