I really like Klobuchar on paper, but the stories of how she treats her staff are horrific and disqualifying. I definitely couldn’t support her in the primary for that reason.
What are the stories?
Ik she has the highest staff turnover rate.
That's all I could find on google. While it does raise some question about the reasons why her staff turnover is so high (and even that, it doesn't even seem THAT high compared to the highest staff turnover in the House which is around .65 IIRC), I would hardly call that disqualifying in itself, unless there are actual reports of bad behaviour which the op seemed to hint at.
