There is still ZERO evidence of any hacking done by any foreign government. All we have is the CIA saying "trust us, we think it might have happened".
His business deals and insider trading is more concerning to be honest, that's where his missteps are most likely to be.
As for the DNC - I think Bernie would have been the anti-establishment change that would have satisfied people but without the ugly personality. It looked like the guy had scruples and hasn't been cashing in all the time.
Hillary and the DNC killed dead any excitement and passion that the dems had. She generated as much enthusiasm to turn out and vote as a wet fish and then did little to help the people on the ground in the important states. Terrible candidate by any measure but especially in a "we want change and are sick of Washington insiders" election. Dems were thoroughly out of touch with real people.
General Flynn wasn't running for election and wasn't secretary of state and any crime or failure of his does not excuse Clinton. The left has to get past this game of trying to find someone worse to compare against. Put up a decent candidate who isn't mired in corruption and is competent, it really is that simple.
