I like most of her policies. The AZ law is growing on me - I just can't get past so many reliable conservative voices who are against it.
That being said, her erratic behavior isn't something you can defend with "well, her positions are good, so we can ignore when she acts insane".
Watch the reporter video. I'm not sure she's stable. Yes, I like her positions. But she's not all there, in taht video.
