Take over the GOP/RNC from the bottom up. Precinct leaders, County leaders, State leaders and National leaders are all elected.
Join your local precinct. Get MAGA precinct leaders elected who can then elect MAGA county leaders, who elect MAGA State leaders who elect MAGA national leaders.
This has to be done even in blue states because every state has a GOP and even in a blue state, they have as much power behind the scenes as red states with their votes for inner party people. These inner party people have a lot of say in who runs as official GOP candidate in the primaries.
The people in the two gop.com links above write the platform, bylaws, they have the databases and they hold the purse strings.
Been there done that it doesn’t work. Spent years on the Hillsborough County FL Republican Committee. It was crooked back in 1986. Only to get my butt busted trying to go against the state committee’s “recommendations”. Follow the money. People like Soros get county attorneys elected because he pumps millions into their campaigns at the state level from his PAC’s. Florida has 55 counties. With most flawed and lazy humans, money talks. Your view is naivete cubed.
