Or not. Early.
Either way, I'm sure she'll have a major impact, but it would be irresponsible to "tease" a possible run and then not follow through, as she did in 2011 (for the 2012 primaries).
Well yes, that too.
I strongly hope she runs. But if she does not, I hope she removes herself from consideration EARLY.
That said. 2016 seems a very good year for Palin.
