Holy shit, get with the times, man. Republicans are not going to pass a law to give the DNC an exception. They are enemy actors. Don’t be surprised when some bygone comity, most recently driven by a need to support their own candidate’s late convention, doesn’t carry forward. Treat them as threats and don’t give them tools to screw you over.

Also, candidate Biden’s team doesn’t set nomination conventions for the Democratic party. It makes no sense blaming it on him.

I never blamed Biden for this. You’re the one who said that Biden’s wins means the people who did this were competent. The people setting up the convention are however, certainly “working to get Biden elected” (the actual people I blamed). Though I find it massively naïve of you to assume his direct campaign staff are just passive onlookers in the process. Even if they were, they should be on it too. If a third party’s incompetence can fuck up your ballot access, double check their work. These weren’t secret dates and everyone knows who’s in charge in Alabama and Ohio.
