Do you really think the GOP is some kind of living stand-alone entity with the ability to choose who runs it?
The GOP is owned and led by demrats thru their surrogates—RINOs. Do you really think they will simply walk away and let conservatives take over?
The fact is, there is no second political party in America today. The opposition vacuum will be filled eventually. I doubt it will include the GOP.
In most areas it is incredibly easy to take over a BPOU. Get a few friends, go to the meetings, vote yourselves in control and take over the BPOU. Work your way up from there. If conservatives really do have the numbers and put out the effort, the squishy elites cannot remain in control.
