I think Sarah was mostly inplying that she will actually endorse a candidate on an official level if and when a brokered convention likely happens.
There is a very strong possibility of that happening, considering the mess that this primary season has become.
I think she meant more than that, and I'm fine with it.
As the party VP nominee in 2008, Palin was in the seat as presumptive standard bearer for 2012. She abrogated that position when she declined to run. Her sphere of influence has dwindled greatly as a result. I doubt the Elites consider her a ‘force’ in the party politics. She became little more than an ‘also ran’.
