Not really all THAT complicated

If Clinton had been elected, and you read that Chelsea had accepted a meeting back in June of 2016 with a Russian lawyer with connections to Russian intelligence to discuss help with the Clinton campaign against Trump, and she'd accepted in her response with "I love it," actually held that meeting, with the Chairman of the campaign present; and then a few months later another staffer pleaded guilty to meeting with a Russian "professor" with ties to the Kremlin who promised "dirt" on Donald Trump, then lied to the FBI about it, do you seriously think there would be any question about whether or not Clinton should be impeached? Not to mention that, in this reverse world scenario, her campaign manager (who'd had to resign in disgrace), and his protege, would be indicted for money laundering after accepting millions and millions of dollars for influence peddling from pro-Russian Ukrainians and Russian oligarchs. 

This is exactly what has already happened with Trump, in the real world. There is clear evidence of collusion by the Trump campaign with a hostile foreign power, including the cooperation in the use of illegally hacked DNC emails, which are a "thing of value" under election laws. Very serious crimes, involving compromising our national interest in favor of the interests of a hostile foreign power, have been committed, and it is all but impossible to believe Trump himself didn't know about it, or that he hasn't been lying about it for months now. Impeachment is inevitable. It isn't really all that complicated.
