OK, admitting ignorance here.
How did a candidate gain control of the Republican National Committee?
The RNC was implemented as the Raise Money arm of the GOP.
Its job was to raise money, not so much as to get candidates elected.
Face it, Trump is the face and The Leader of the New Republican Party, as a result of the RNC’s and the GOP’s refusal to accept this, they are broke.
Nobody on the grass roots level is donating funds to the RNC, most of their money goes directly to Trump and to candidates he has endorsed. Remember Trump’s Seal of Approval, that scared the schit out of the RNC and rightfully so.
In the end, the RNC had to accept Trump as The Face of The Republican Party, or be destroyed. I’m guessing that Trump’s meeting with McRonmey a few weeks ago set up the conditions and demands made by Trump if he was going to align himself with the RNC and basically bail them out financially.
As a result, Trump-and-Trump now control the RNC, without them it would be no more.
