Delegation, yeah. Back in 1990, while I attended the Defense Intelligence College, we had a little old lady speak to our class one day. She was retiring from long service in the CIA. She looked kind of like Betty White. She had been one of William J. (“Wild Bill”) Donovan's original OSS agents during WWII and was an operative of the CIA from its foundation. She had been a CIA Station Chief in a certain country during the early days of the Cold War...and to know which country was to know she'd been deeply involved in the undercover war between the US and the USSR. I don't know if there was ever a real "James Bond," but she had definitely been the real "Felix Leiter." We sat there in stunned awe of that old lady.
There were still operations she was "not at liberty" to talk about even to us, but she had some interesting stories, such as being in the room when Kennedy decided not to support the Bay of Pigs operation. Most interesting was her insider opinion of various presidents and CIA directors over the years. The CIA had despised Carter and Stansfield Turner, but they'd loved George Bush and Ronald Reagan (actually, Reagan had been a great guy to work for, much better than Carter as a boss, even in my opinion, although I preferred Carter's politics to Reagan's).
But very interesting was her revelation that in Reagan's second term, because of his failing mental capacity (which was still generally unknown at the time). the CIA had stopped regularly briefing him or going to him for instruction. They took everything to Bush, who provided the "Executive Officer" direction required by law.
Biden had been my last choice for a Democrat candidate. Harris had been my next-to-last choice.
That was my only reason. My great fear was that Trump's intention was to break each branch of government for his own purposes. I don't think that's the reason of the left-wing extremists insiders running the DNC, though. They have an agenda that isn't my agenda or the agenda of most Americans.
If Trump weren't running, I'd be hard-pressed not to vote for any other Republican, although DeSantis would give me great pause. But I don't think DeSantis would destroy the government, so we'd recover from his presidency.
