Speculation based in logic is called a hypothesis, which is what I offered. There is decent reason to believe that the Russian interference in the 2016 election was based in political motives:

• The act of hacking into election machines is an inherently political act;
• The testimony that Comey gave, under oath, suggests that this is not the first time that Russian individuals have interfered with a USA election;
• Russia also hired trolls to create anti-Clinton fake news over the course of the 2016 election.

Saying that the truth can’t be proved is not a reason to stop seeking the truth altogether. You talk about logic but offer none of your own, only empty platitudes.
