Although it might never be proven, there’s no doubt in my mind that the nonsecure server was set up so that clinton could sell the classified information. The clinton presidency was marked by continuous sales; Loral, the missing laptops in the Los Alamos fire, and all of the dealings with China through its agents, the attempted sale of Long Beach port to COSCO, not to mention all of the local sales by the clintons themselves, such as coffee with the prez, Lincoln bedroom, seats on AF1, etc.
Why would anyone think a second clinton presidency would be any different?
I think it was set up so the Queen did not have to be bothered with carrying two phones. She could have carried a state department phone and a personal one, but she did not want to be bothered with stuff the little people had to do.
I don’t imagine it was anything more than that. Hubris.
