I personally think her vote sends a good message to other members. Yes Trump has issues and has done things a president shouldn't do, but the reason they impeached him was wrong. That's my view.
My personal opinion is that Trump and Biden are guilty (like most ) of the same thing. The difference being that Trump came in as a businessman, where as Biden has spent his whole time in Political office doing exactly what they are accusing Trump of.
Biden is as corrupt as Trump, did most of it during his lengthy political career and most of Trumps worst actions occurred prior or in a different time of life. Doesn't make Trumps actions any different, but in my opinion the Democrats tried to weaponize impeachment whilst having just as sordid a history of corruption especially in biden's case.
Again I can't vote in the US election and I am just an outsider, but anybody who thinks one side is magically better than the other in the corrupt system, is purely bias. Same shit, different party, it just comes down to whether youn want a guy who can get shot and pump his fist as your leader or Kamala Harris at this point. Same thing happened in Aus a few years ago where we had our first female Prime minister after her party replaced the elected leader. You need a strong person to take that first go at it and I don't think that person is Kamala.
