The Economist did a fascinating dive into the gender voting gap. One thing they noted that the gap is really between men who simultabeouslu characterize themselves as both very masculine AND not being masculine enough. Basically, dudes who are insecure about their masculinity.

All that to say, I think if you edited this down it could be a painfully good attack. Having a jacked wrestler compare him to Dolly Parton? Can't think of a more pointed attack.
