Correct. If Sarah Palin were interested in wielding political power, she wouldn't have resigned her governorship midway through the first term.
She is very interested in taking on television appearances and speaking engagements, snarking about liberals, and getting paid for the effort. She's found a way to make a very comfortable living while doing something that she loves, and recognizes that occasionally making noise about running for office is an effective way to reinvigorate her brand. She did the same thing ahead of the 2012 presidential race
when she rented a bus and drove around aimlessly for a few days
as part of a cheap publicity stunt.
Sarah Palin has put zero effort into readying herself for a presidential bid. She has no financial backers, no support infrastructure, and even fewer
policy credentials than she had as the vice-presidential candidate in 2008. She is not "back"; she is not running for president.
