The best answer if you end up being one of the people that wonder what Maine sees in this man. The best thing to do is to stop letting yourself be told about him and go talk to him or listen to the man himself.
If Graham has someone who isn't himself advising him. They are both an idiot and a genius. Which kind of makes me think it is him. Kyle Kulinsky of secular talk the other day played a clip from an interview with platner where he spoke about masculinity and toxic masculinity. It's at the end of the segment. I think that clip illustrates fairly well what people see in him.
As to him being another fetterman. I'm not going to say Graham will be perfect. He won't. He's going to disappoint everyone at some point. But he has literally called fetterman out personally. Fetterman didn't just become an asshole overnight. It wasn't the work of a stroke or anything like that. The man was a well-known bully and asshole in his own community. Even if he was a relatively successful mayor. He literally chased down and tackled an innocent black jogger holding them at shotgun point. Assuming that they were a criminal. The fact that he was bullying Mehmet Oz at the time was what everyone literally liked about him. They just thought it would never be turned on them. I'm not sure honestly what would qualify as anti-fetterman. But Graham is somewhere on the opposite end of the spectrum from fetterman. He's willing to put himself out, be vulnerable, and explain himself. Apologizing when necessary. Something that fetterman has repeatedly refused to do.
