This Russia conspiracy theory stuff from Democrats is an attempt to discredit Trump so that he can't sell the country on prosecuting high profile Democrats.
The most serious crime to date (that the public knows of) was the Obama admin selling ambassadorships and other high level positions to the highest bidder. That is something that could very well land Obama himself in prison.
New Guccifer 2.0 Leaks - PAY FOR PLAY - Top DNC Donors Were Awarded Federal Posts Following Donations
Top individual donors to the DNC. Look how many got positions. What are the odds??? Illinois gov. Rod Blagojevich is in prison right now for this very thing. He sold Obama's senate seat to the highest donor and then Obama did the same thing in DC. It is entirely within the realm of possibility that Obama could be in prison a couple years from now.
