I’m not saying it will work necessarily - just saying that the idea has never been to convert the RINOs - it’s been to outnumber them in Congress and/or have a titular head of the party who is conservative (that would be a nominee/President as a conservative).
There are no guarantees, and yes, the allure and the aphrodesiac of power in DC is very powerful and corrupts many.
problem I see is many run as conservatives and aren’t. or change.
it’s so terribly frustrating!
