I think we all already knew her chance was blown:
In the immediate aftermath of Floyd’s killing, Klobuchar’s time as chief prosecutor for Hennepin County came back under scrutiny, specifically the lack of prosecutions she pursued in cases of police brutality....So what I hear in her effort at a high-minded statement is an undercutting of the other women who are in the running. First, Elizabeth Warren — who is not a woman of color except in her memory of younger days when family lore and a desire to identify were enough. Why step on her chances, Amy? Second, all the various black women who are in the running. Amy is ensuring that when one of them is picked, everyone will believe they were picked because of their race.
Asked if those questions about her past record on police brutality would have made it harder for her in the role of vice presidential nominee, Klobuchar said Thursday: "I think I could've functioned fine and there's a lot of untruths out there about my record and now is not the time to debate those."
