I'm hoping the same. Given the time it took for Sarah to reply to their invitation, it's a good bet that she and her strategists thought long and hard about this choice.
I would hope that they decided to have Sarah join the re-branding tour so that she could control that "re-branding", if there is to be such a thing.
In the long view, it may be better for the party, and for America, to have her in a leadership position among senior opinion makers on the right, than to have her create a schism on our side by standing out.
There's no doubt whatsoever that she's the headliner of this tour, despite what the inflated egos surrounding her may think of themselves.
By the time this re-branding tour is over, Sarah will have cemented her rightful place as the chief standard bearer of the patriotic right, and will have focused our side on core conservative principles again.
While she's at it, she may unavoidably expose many of her fellow opinion leaders as the milquetoast RINOs they are.
