No duh, way to get off point. Try to remove the Cruz fog that is rotting your brain.
As president he would be able put who he wants into the RNC. Even if he couldn't and did, it doesn't compare to the voter disenfranchisement that is happening.
Also, look in the mirror and behold the underwhelming spectacle of a cultist before you toss around words like messiah.
Actually, no he can't - not unless they agree. Here is the pertinent rule:
"(a) The officers of the Republican National Committee shall consist of:
(1) A chairman and a co-chairman of the opposite sex who shall be elected by the members of the Republican National Committee. ...The chairman or co-chairman may be removed from office only by a two-thirds (2/3) vote of the entire Republican National Committee.
" So unless Trump can get 2/3 of the RNC to go along with him, he can't oust Priebus, and unless he can get a majority of the RNC to go along with him, he can't get his own person installed. Now since Trump has made such a point of insulting and pissing off every member of the RNC, how likely do you think it is that they would want Trump supporters in those spots?
