MOLLIE HEMINGWAY (FOX NEWS CONTRIBUTOR): Joe Biden was really smart when he picked [Kamala Harris] as VP because she's this kind of insurance policy against getting him out. But it's also true -- I'm not sure Nikki Haley is the best person to prosecute this because she has made so much of her campaign built on her identity. She's sort of the Hillary Clinton 2.0 of the race where she talks about how she's better because she is female, I love being female, but this is not an argument really to win the GOP primary but also, you know, this is -- identity politics is not something the Republican party should be doing.
