It's important to understand that when a Mayor or other public offical repeated attempts to obscure and destroy records owned by the public that is a huge red flag. The same can be true when he intentionally sabotages the collection of public records or directs public business to a personal email account that was also used to manage campaign solicitations. It's also pretty stupid too. You see because if someone is conducting public business within the same medium they are discussing donor payments or how to keep a volunteer quiet about a really fun night they had, it becomes more difficult to plausibly deny quid pro quo or the selling/leasing of public property in exchange for campaign payments or other favors. It becomes even worse if that someone falls under the belief that the email was hacked and those emails land right infront of a law enforcement body with a responsibility and mandate to investigate and prosecute instances of public corruption. I'm sure other types of complications and criminal investigations that could arrive during these processes as well. This is all theoretical of course, but its fun to think about what would happen if that public official just decided to say "fuck it" during an overcaffinated "excited" episode and started dishing dirt on his donors, political allies, and various staff from over the years in an attempt to save his own ass and carve out some badass redeeming starpower for after everything shakes out. Hell, to think about it, bringing down a corrupt party structure that you never really bought into might even be a little fun.
