You need to compare her vote total against Biden's currently. I suspect she is still running behind Biden. She certainly does not help Democrats with the act she puts on through the media.
One of the most frightening articles I read in a while was speculation that Biden could appoint Gillibrand to a cabinet position, thereby opening the door for Cuomo to appoint AOC to the Senate. I sincerely hope the governor is not that stupid.
I liked the theory, but not really it turns out. I suspect unlike most CD's in NY, AOC's challenger might do a bit better than in absentees than in the vote so far, but basically, the Torie Dems in NY-14 are very thin on the ground. The reality is that a more than negligible number of Dems in NY-14 are closet Pubs, or persons of color who cotton to the Trump macho act.
