That "PoundMeToo" seems to me to be just as wrong as the "MeToo" meme. If MT implies that you automatically believe a particular person, the PMT implies that you automatically don't believe them. I think both approaches are equally wrong.
I just say PMT because I don't like the hashtag. My used of PMT is the same thing as MT with a touch of sarcasm/skepticism. My fault for not making that clear.
As for how this relates to the Jr. Senator from AZ, my only pertinent observation in this thread is that it doesn't matter if I believe her, I'm just making the argument this revelation will be a net loss of votes for somebody who had two difficult elections to the House that she won, and a Senatorial election she lost.
Leftists still won't vote for her whether they believe her or not, and the conservatives just find this pandering another reason to not vote for her.
