The guy has always been a controversial figure. Never forget he’s also the first president to get a mugshot picture in 2023.
there's being "controversial" and then there is sucking another mans dick. his entire brand since the 80s has had him as an avatar of the average joes aspirational masculinity in contrast to a bunch of soft stupid pansies (in business, elite social circles, his TV show and then politics.).
so every bit of "bad press" has always worked in his favor, esp on the campaign trail.
the thought of a dick ever going in his mouth, is a legacy killer.
