You really have to respect the opinions of a guy many rate as a worse president than even Jimmie Carter. Never said a peep during Obama's administration.
Two possible reasons: 1. It wasn't clear at the time and it would be aggregious for a sitting president to make such a bold accusation without concrete evidence. 2. Trump effectively shut down any ability to make such a finding public when he, himself, made his own accusations that the democrats were going to rig the election. By doing this obama couldn't say anything other than that the elections couldn't be hacked/rigged. Perhaps trump said this knowing the Russians were hacking the election; he's very clever at manipulating the media, his base, and the left into a frenzy.
Debbie Wasserman was chair of the dnc, and her accounts were being managed by/had access to by the Awan brothers. Her passwords and the passwords of half of congress were available to be had. What did the fbi find when they investigated the dnc computers looking for digital fingerprints? Oh, that's right. Debbie would not give them access and the fbi would not get a warrant so we just went ahead and assumed the Russians hacked it. Another Hillary-led fbi investigation. Also known as "you can't look there."
Bush is on my list of "Worst Presidents" and the only Republican. Even Jimmie Carter isn't on it.. (I see Carter as "innefective" and "milktoast". That's waaayy different from Bush and Odumbo and their "doing great harm to our country".) With the Bush and Odumbo administrations, America has suffered greatly. Shame on both of them!
Obama didn't defeat Jeb and put an end to the entitlement program, the way Trump did. Trump ended the Clinton entitlement program too. Lot of butt hurt floating around out there.
If you were unhappy with Bush and Obama, hold on to your hat, buddy. This is going to get pretty bad.
