Yes, but being as she can’t trust the Republican party, I don’t think she will run.
She knows the GOP-e despises her.
If she makes a big move to personally campaign for many Conservatives in 2014, then you will know she is testing the waters for a serious run in 2016.
Her strategy in 14 will be to mainly go after the GOP-e in order to push "real" Conservatives against the RINOs. If that effort is successful, then she will move early to run.
GOP voters vote for the GOP because they don't want to vote for domestic communists.
With Palin as head of a new party with a mission to destroy the federal apparatus in DC as the primary plank in its platform, there would be very few GOP voters that wouldn't jump ship.
