Having worked on an election, I know you will always have problems considering the scope and logistics. Different types of problems but it makes it more difficult to visualize a mass conspiracy (would have to be gigantic to have simultaneous conspiracies or a giant one that covers all the states...).I'm not understanding the relationship you are drawing between irregularities and Sates running thier own elections. The lack of centralized governance can create just as many problems as it solves. I do think there is some prima facie evidence that requires investigation (e.g. software issues, equal protection clause, etc.). Again, I don't believe the outcome will be changed but if something was illegal or administratively improper it needs to be addressed and remediated.
Not directed at you but at Biden...resolving political rifts? How? He and his party berated, belittled, shamed, cancelled, and dismissed almost every constituent represented by leaders on the other side of the aisle. Biden and his party demonstrated an unprecedented lack of cooperation over the last 12 years...getting progressively further apart. There is zero argument to the contrary on that point. The populous is the only body of people who can settle the divide. Politicians are presently incapable of achieving that end.
The concession speech...neither you nor I can recall that absence because I don't think it ever occurred in our lifetimes. That said, it is customary not a constitutional requirement. Trump seems to believe that the decisions of the courts may influence the outcomes. I don't. I can understand his reluctance to concede. I'[m betting we never hear one, which I think would be classless considering the custom. I am old enough to remember Gore retracting his concession to Bush.
Perhaps we need to hear LESS from politicians. Administer our respective countries and debate specific bill based on the pros and cons of the legislation: work on merits and what will be best for the most and demonstrate / justify what is being done.
And it is not just the politicians. Not sure if you saw it, but we just went through a very rapid "issue" where Whole Foods banned employees from wearing poppies in advance of Remembrance Day, but had it overturned. I guess anytime you have people with different views, there will be conflict. The challenge is how to minimize the conflict and the personal attacks, sticking to the issues. You are right, it will come down to individuals showing a basic level of respect for each other, and hopefully that basic level will grow over time.
