I mean, he’s right in one way, you certainly ought to be able to talk about who you are voting for without fear. Communication, debate, and choose for yourself. So really the far right are just reaping what they have sown, I don’t see how he can blame the ad.
I just want to point out that both the abortion amendment and the marijuana amendment here in Florida had bolded text on them added by the state - in the case of the abortion one, including the dubious claim that “it will increase the number of abortions performed” and both still won the popular vote, more in favor than opposed, they just didn’t make 60%.
