A. That is exactly what palin did in 2008. Bear in mind that you not I declare that to be not noble.
It was only for two months.
B. After only two months quit in 2009 she has gone on a book tour, started a TV career on FOX, started a TV series, been paid for speaking engagements and spoken on behalf of a select few politicians. She has not run for higher office.
All the things that you list would help prepare for a presidential run.
When pointed out to you that after she did quit Palin has spent most of her energy pursuing financial gain via media you angle that fact to fit an undeclared candidacy.
That is the problem. The facts are the facts. Your spin on them is either hypocritical or supposition.
