Does Sarah have handlers? I don’t think so, if so, who are they? Personally, I think her strategy is one of her own making, totally outside the box and one that has the “elites” totally confounded. I am willing to trust her judgment, she has a successful, winning track record.
As far as the corruption angle, how can she fight the corruption other than point it out? The only ways I see she can do something about it is by helping like-minded conservatives get elected and becoming president. She did it as governor, so again, she has a track record of winning.
She already has more supporters than anyone else being talked about for the nomination.(and growing) Timing is everything, imo.
