OK, now answer my non-partisan question Liability.
Reading is fundamental. I ALREADY answered "your" question. I already noted (and got mocked for asserting it) that I believe she is going to make a run for the Presidency.
Is her resignation the best way to go about doing that? I dunno. Arguments can be made both pro and con.
Is she presently the best conservative and/or Republican candidate for the job? Not necessarily. I believe she has MUCH to learn, first.
There you go, a much better answer than before.
I personally think she was doing it to spend more time with her family. She does have 5 kids, a child with Down Syndrome and a grandchild. I would think the big arena of political life got to be too much for her, and she couldn't be with her family like she needed to be.
I know how hard it is for parents out there, but when there is a special needs child involved it's even tougher for them.
I too think the Republicans could choose someone better to represent them in the 2012 Race, just not sure who yet.
