She's a Republican from a macho state, which would make a lot of people who might have reservations about voting for a woman seriously consider her in a way they would never consider a woman like Hillary, who's a liberal Democrat representing a liberal state that is unpopular among middle Americans.
I don't fully grasp what you are trying to say here.
KBH: Conservative Republican from Conservative state.
HRC: Liberal Democrat from Liberal State.
And who's unpopular among middle americans? Hillary is polarizing, and most people either love her or hate her (I'm in the middle actually). But in the last Gallup poll, she had a 56% personal favorability rating, the highest that it has been since she was first lady.
