People want to say that the Russians hacked Hill's Campaign but insist that nothing leaked out of her home brew, bleachbit, wiped it with a cloth or somthing server from when she was Secretary of State.
Why does anyone think those two things are both true?
I don't think there's anyone asserting that Clinton's home server was secure or that nothing was stolen from it. It's really impossible to know. It is, actually, perfectly feasible to run a private email server securely. But you'd have to audit the server, prior to it being wiped, to know if that happened. But that isn't the basis for claiming that the Russians attacked the election to help Trump.
