Recall please Grover Norquist. In the 90s and 2000s he leveraged proximity with the post-Reagan new conservative wave to grow a relatively modest org, Americans for Tax Reform, to a near universal policy chokehold on the Republican party.
Through a socially viral "no net new tax" promise, once Norquist secured pledges from party leaders, essentially all federal elected Republicans had to pledge as well. They were otherwise threatened with losing endorsement from Norquist and faced being ostracized and primaried. The leaders themselves were then caught in the net and none felt like they could break.
ATR influence has waned in the face of MAGA's more populist fiscal liberalism, but that was pretty much just one guy.
Extend that singular goal to a network with a narrow and aligned interest, and it can be very effectively maintained with intelligent and shifting messaging and reputation management. Consider how people like Loomer and Raichik that have emerged, not through established power brokers, but organically through social media platforms, and the significant influence they possess even in the White House.
