An irony of the escalating hysteria about the Trump camp’s contacts with Russians is that one presidential campaign in 2016 did exploit political dirt that supposedly came from the Kremlin and other Russian sources.
Friends of that political campaign paid for this anonymous hearsay material, shared it with American journalists and urged them to publish it to gain an electoral advantage. But this campaign was not Donald Trump’s; it was Hillary Clinton’s.
And, awareness of this activity doesn’t require you to spin conspiracy theories about what may or may not have been said during some seemingly innocuous conversation. In this case, you have open admissions about how these Russian/Kremlin claims were used.
