The thing about Hillary's emails? We knew exactly what she did. What do we know about the Trump/Russia connection? Nada. Zero. Zilch. It's 100% speculation. You've got dirt on a few former aides and nothing on the man himself. That is a YUGE difference between the Clinton and Trump investigations.
They were both based off of speculation though, namely the contents of the emails. The difference just seems bigger to you because you have a strong bias towards Trump.
Actually, Comey actually stated that Clinton broke the law. He inferred that she shouldn't be prosecuted because no (at the time) "reasonable prosecutor" (codespeak translation: No prosecutor on the payroll of the Obama Administration) would prosecute her because, well, reasons.
We also know that there were
hundreds of classified emails shipped to her private server, which is not only illegal, but also a huge security risk. We also know that at least
five foreign countries have hacked into her server and obtained classified information. We also have testimony from the technician that stated that he purposefully deleted and destroyed emails after Congress subpoenaed them, which in of itself illegal.
As for Trump, we have an FBI who leaks faster than an underwater house. And, for all those leaks, all we have is 1 National Security Adviser who lied to the VP, 1 Campaign Manager who had known, legal business dealings with Russia, and 1 indirect volunteer adviser who had business dealings with Russia, legality of which is legally questionable (although, not really). That's it. We also have several top Obama officials who stated
under oath that there were
no evidence of collusion between Trump and Russia.
So, yes, there's a huge difference there.
