Her campaign ammo has been to project herself as a non-politician and complain about her opponents being "career politicians" to deflect the fact that she has very little in political advocacy (even in voting), so why would any sane person take what she says at face value? And the fact that she backed and worked for "career politician" McCain (who has more years in office than Campbell and DeVore combined!) just makes her a two-faced phony... I guess some career policians are more acceptable when you're not running against one, eh?
So with little in her political resume, what she has advocated for in public life is very important, and starts to paint the picture of the REAL Carly Fiorina, not just some image designed by her and her political consultants.
INTEGRITY... a trait still important to some Republicans.
