I don't know, it sounds like a slightly better worded version of "I know great people, they're the best people really, and I am one of them". They're extraordinary and they are his friends => wow, that must be quite the great guy, or he wouldn't have those kinds of friends.
Scientists might not directly have political influence, but especially the very successful ones are well-connected and have friends in the media. If you have lots of money to spend and you want to buy good will, wouldn't you just spread it? If a journalist ever thinks about you and talks about you at a private party, what better could happen than a science guy saying "oh I know him, he funded our important research" and an author saying "oh, yeah, that guy, he donated money to some literary program" and a finance guy saying "wow, yeah, he's very successful".
I find that a much simpler explanation that fits well into the picture.
All I was really saying was that maybe he believed this himself. Like his mum paid for an expensive party and invited the cool kids and they were mostly polite and now he thinks they like him and he’s part of the group. Key difference being belief in his own delusion, before bragging to others about being one of the cool kids.
This would make claims about his "extraordinary group" of friends make a lot of sense. He might have associated with those people thinking that it made him feel and appear to be an interesting, intelligent, overall better person. Seems like exactly what an "intellectual imposter" would do, more than someone trying to build a personal shield.
Besides, we all know scientists have no political influence worth harnessing.
