It's been no doubt said countless times prior itt, but Nick's biggest problem is that he doesn't actually know how to make his movement appealing to anyone outside of it. On the one hand, he wants to get the Groypers into the mainstream GOP. But on the other, he wants to maintain the edgy, politically-incorrect nature of his "political dissident" internet origins. Despite his efforts, neither can work together because of their nature of being diametrically opposite of each other. If Nick seeks to have any chance of having the Groypers become household names in regards to politics, he's going to have to fix his optics and make his platform more appealing to the general American voting constituency. No one, not even the most conservative of politicians on Capital Hill, are going to find his "funny" or "ironic" references and IRL trolling interesting, productive, or most importantly, mature. And yes, this pathway will entail him having to work with, or at the very least tolerate on a public level, the "based black conservatives" like Brandon Tatum and Candace Owens. People may complain about those two being "run-of-the-mill" milquetoast Republican types, but they are both competent enough as political commentators to convey their views and philosophies in a way that has not only garnered mainstream attention from citizens to Senators, but also make people who previously never cared about politics to pay attention and learn more about it for themselves. That is good, prosperous political influence. The way I see it, and what I imagine most politicians would see if you asked them about it, all Nick can do is cuss people out on Twitter, transition his political aspirations from 1488 to 1776 and back again on a whim during his shows and speeches, and continue to further the hypocrisy of his own vices amid his showmanship of being a "based tradcath".
But then again, even if Nick had the opportunity to send the Groypers into a government institution, local or national, accusations of him and his ilk being "ghost skins" would probably be his coup de grâce from the mainstream political arena.
