What are you talking about? Who is 'you guys'?
I've been complaining about the postal service for years. I'm not going to start blaming Trump now.
But there are metrics here. This terrible political appointment made changes that had an immediate and measurable affect; lowering on-time delivery of first class mail by about 10%.
Now, as I said back then, anyone who wants to get rid of Trump should have taken this as a warning - especially combined with Trump's constant drumbeat that mail-in ballots are going to be fraudulent - to not to risk mailing their vote. But that doesn't change the fact that this asswipe was deliberately slowly down mail service just as people were requesting ballots.
