Okay... let's take a look at this
In 2015, the DNC servers were hacked, presumably by Russia though no evidence has been provided. The hackers had access to the servers for nearly a year. The DNC refused to turn the servers over to the FBI and instead used a private company that worked for the DNC to investigate. 10 months later (Aug 2016) they gave their report to the FBI. In their report, they fingered Russia. So no, the FBI can't conclusively say Russia hacked the servers because they were refused access to them and are depending on a private third party opinion.
Thanks to wikileaks, we know that back in Dec of 2015, the democrats were scheming to take Trump down by claiming ties to Putin. They originally planned the attack to take the heat off Hillary and her lack of a plan for dealing with ISIS. They even got Republicans who supported Cruz and Rubio to be their useful idiots and run with unfounded allegations.
On July 19th, 2016, Trump wins the RNC nomination. In August, top ranking democrats demand the FBI investigate Trump for collusion in the Russian hacking. The FBI opened an investigation. Now bear in mind, this was a criminal investigation opened based on allegations from democrats who had been actively working to tie Trump to Putin since December of 2015. Recall as well that the FBI allowed the DNC to have their servers investigated by a private firm that worked for the DNC and did not insist upon access. They were in effect investigating a hack they were not allowed to investigate.
That's not even remotely normal. It appears the FBI opened an investigation not based on evidence of a crime but to see if they could find evidence of a crime. That's the type of behavior you see from totalitarian regimes.
Connect the dots, folks. It seems the swamp is even more putrid than we ever imagined.
