Actually, as politics goes, all she really needs to do is raise lots of $$$ and not support any RINO candidates. That alone will tilt much of the critical infrastructure of the party her direction.
But you are correct, if she can leverage that to solid gains for the GOP (the bigger the better - perhaps even a reversal in the House) then she will have the party dancing to her tune.
To accomplish that, all she has to do is have a well planned Tea party and a pancake breakfast or spaghetti dinner for a congressional candidate. Maybe 5 or 6 of the same for a Senator.
And for now, the message is easy:
1) I am plain folks like you
2) I support the military
3) Obama is screwing things up big time by .....
4) We can still stop this assault on freedom by electing solid conservatives who will work to reverse the Obamanation
agreed except she will support some rinos, at least here in the NE (NJ).
Sarah must be a kingmaker and rake in the IOUs.
That’s JMHO of course and I’ve never run or won an election.
