Every candidate does some version of this. The question is since Romney already has a rep for insincerity among his base, will the normal post primary moves to the center hurt him?

Etch-a-Sketch

Quote:
Two constituencies that President Obama is holding onto about as strongly now as he did four years ago are voters under 30 and Latinos. In what is probably not a coincidence, these two constituencies are the targets for the first two major Mitt Romney Etch A Sketch pivots of the general election. After having repeatedly denounced any need for the federal government to subsidize tuition costs during the primary, Romney has now endorsed Obama’s call for extending lower rates for federally-subsidized loans. Romney says he supports the measures “in part because of the extraordinarily poor conditions in the job market.” Apparently, he has been informed of the poor job market since wrapping up the nomination, when he was still advising graduates concerned about debt to acquire a high-paying job.
On immigration, Romney is making the turn a little more slowly, as you’d expect, given the sensitivities involved in holding together his base. Romney has deputized Marco Rubio to craft “his” own version of the Dream Act, a somewhat more restrictive version of the reform that Republicans in Congress killed and Romney opposed in the primary, when he positioned himself on the party’s right on immigration. Romney is “studying” Rubio’s bill.


"When the snows fall and the white winds blow, the lone wolf dies but the pack survives."
Winter is Coming

Now this is the Law of the Jungle—as old and as true as the sky; And the wolf that shall keep it may prosper, but the wolf that shall break it must die.
As the creeper that girdles the tree-trunk, the Law runneth forward and back; For the strength of the Pack is the Wolf, and the strength of the Wolf is the Pack.
