What is the point of wasting a write-in ballot on someone who isn't a candidate? If she were running a write-in campaign I could understand, but she isn't.
Also, if your principles won't allow you to vote for Romney, why would you write-in a non-candidate who actually will be supporting and campaigning for Romney? You do realize Palin is ABO and is going to support Mitt as the GOP nominee right?
As far as Sarah Palin goes, you note that she is supporting Romney as an ABO. Haven't you sensed her total lack of enthusiasm for Romney since Day 1 of the campaign? I'm guessing that her schedule will suddenly be full on all the days which Romney would like her to appear with him.
