Why did the Russians want Trump to be president? Because the?

Trump's trade affiliations with Russia date back long before his candidacy. Include Trump's highly suspicious behavior (such as lying about return releases, etc.) and it's safe to conclude much more than meets the eye. Trump asked Russia to interfere in the elections on his behalf (they did). Trump and Putin have had secret talks, etc. I look forward to many responses once I am no longer protected by the office. It is aimed at eventual liability.
