The best way to do this is for conservatives to:
1) Get involved in the GOP apparatus at the county level. Flood the county Party with motivated conservative activists who will be able, at the next county convention, to get elected as precinct chairs and on the Executive Committee (or analog).
2) Once the counties are on board, have the ECs for each county network with each other to promote and elected solid conservative candidates at the state level.
3) Once the state level apparati are taken over, conservatives in each state Party then network with other state Parties to come to a consensus on solid conservative candidates, and then the national Party will be open to taking because it is representatives from the state Parties who have the bulk of the votes needed to elect the national Executives, and who decide who will be on things like the RCCC and RNSC and so forth.
All of this that I've outlined above could be accomplished, in most states at least, within two years. In the meantime, conservatives can network with each other to operate outside of any Party apparatus not under our control yet. For instance, instead of giving money to the NRSC and RCCC, we can develop our own parallel structure and decide who to give money to, in the primaries too if a challenge is needed to knock off a RINO incumbent.
This talk of another "conservative third party" is foolish, unmitigatedly stupid nonsense. There'd be no better way to ensure Democrat domination for a generation. Why waste our energies on third parties which are generally just ego trips for vain individuals who want to get attention to themselves anywise?
A serious threat to break from the Republican party is far from foolish. The Republican Establishment holds disdain for every day Conservative voters - they just want our money and our vote. As far as a stance on the important issues go - the Repug Elites want Dem Lite - play nicey nicey. Don’t fight against the Illegal Alien invasion, move to Socialism Lite - yada yada yada -— THE CONVERSATION must be changed with an ‘in your face attitude.
The Conservative Cry must be ‘Lead, Follow or GET OUT OF THE WAY...
Your plan to retake the Republican Party is a good one - but the other end must be worked — push - shove the Elitist - organize and SHOW that the everyday ‘men and women’ of the Conservative movement are WILLING TO BOLT if not allowed to move the Republican Party back to a Conservative stance.
In short - No Threat - No Win.... continue on as usual.
