if Seth Rich was the DNC leaker, does that imply that Trump wasn’t colluding with the Russians?
Not necessarily. That is the same false dichotomy repeated constantly in the news and social media. The two can be mutually exclusive. Assuming there is solid evidence coming forth, Seth Rich could’ve leaked the emails to Wiki Leaks and The Russians could’ve cyberattacked govt officials via hackers somewhere in Siberia. Nothing has been leaked on the Republican side but that could still happen, given the possibility that the threat of a leak is keeping them in line.
