I believe her little ditzy bit is all in act...
She perfectly stoked the fires that really put the Tea Party on the map,,,albeit briefly...even though it was really created by Ron Pauls "Hope for America" campaign...
That;s not something a dumb person would have the presence of mind to do...
She also...quite quickly...deduced that the republican party just wanted to use her as a face and symbol (dems trotting out a black president we need to trot out a woman vice president to match) and decided not to play along...worked out well for her...
When you think about it...shyt is

...she pretty much was hand picked by republicans to play a certain role to get them in the white house...decided not to play that role...stoked the fires of a movement that existed before her (tea party) that split republicans to a point that they still haven't recovered from...shyt if you ask most people they think Palin came up with the tea party out of thin air...
That's the drug game equivalent of a corner dealer getting invited into a cartel...starting an internal feud...ruining the cartel...then walking away with million of dollars and fans and a reality show and a show on a news network like

Bonus points for getting Glen Rice to float that story out about them so she even got the "can't say I don't like black people cause I fukked a black guy" card...
A genius...probably not...but dumb...no way...she's had WAY to many things turn out good for her for and her family for it all to just be luck...
