Standard presidential strategy (pre-trump) is to "run to the center" once the primaries are over. Yes this is disappointing, but I'll judge her by her actions. She also didn't attend Netanyahu's speech, but that could just as easily have been travel logistics or it could have been a snub to Netanyahu who is courting Trump and the R's.
She's not my favorite candidate, but she's miles better than Biden, and Biden's a light-year better than Trump.
