Why Tara Reade's Allegations Against Joe Biden Matter: Even If You Want to Wish Them Away.

Joe Biden should not be the "presumptive" nominee, let alone the actual nominee. He has run at least two previous campaigns which he lost (1988 and 2008). His campaign was considered dead until Barack Obama made a few phone calls which resulted in the opposition pulling out. Sanders ended up putting his campaign in limbo, although some die hards plan on voting for him if they can in upcoming primaries.
But Biden's ascendency has made it even more obvious that the primary process is a sham. An otherwise dead candidacy has become the "presumptive nominee" while someone who ran a couple of the most popular campaigns ever is shut out of the process. Not that this should come as a surprise for anyone who is a true progressive since the Democratic Party has long held a disdain for anyone who is truly progressive.
Saying that Biden is like FDR is a total joke since the candidate politically most like FDR, Sanders, was shut out of the race. FDR had to fight to get what little of his New Deal agenda he could past the establishment Democrats of the 1930s and 1940s. But all that is not as salient as to WHY Biden should not be the nominee.
There are loads of reasons Biden should not be the nominee, and Tara Reade is only one of many examples of Biden's issues with "unwanted attention" to women. It is not nothing anyone familiar with Biden didn't know: as this clip from John Stewart's Daily Show from 24 February 2015 shows.

It's one thing to try and write off Tara Reade, but Reade is in no way the first unlike Christine Blasey Ford, Brett Kavanaugh's accuser. These accusations against Biden are nothing new. If anything, they are so prevalent that wilful ignorance by Biden supporters makes their #metoo hypocrisy nauseating.
Although, one can accept Biden's being as bad, if not worse than Trump, yet also be willing to vote for Biden by showing their Trump Derangment Syndrome. The simple explanation is that "Trump is bad" works for them.
Not that there aren't alternatives. Sticking by Biden is where the hypocrisy is most annoying given his history with this issue.
I Demexited in 2016. Although, I registered Democrat again to vote for Sanders in the hope that might make a difference (so much for your argument for "Closed Primaries"). True, registering as a Democrat was a waste. I will again vote Green this year since it gets harder and harder to vote for a duopoly candidate.
But don't blame those of us who are willing to vote Third Party if your candidate loses. The writing is on the wall for Joe Biden. It has been since the failed effort at impeachment made it clear that Biden was as corrupt as Trump (still crickets from Burisma in regard to my job application). Biden is a loser. Biden is even more of a loser in light of the current situation with Covid 19 (I felt a need to be more specific since Biden is a loser in general).
And don't blame anybody but yourselves when Trump is reelected.
