I think the Dems in the House have to pursue an airtight case(s) against a limited # of crimes committed by Trump, selected from but not necessarily limited to: Russian collusion, obstruction of Justice re RussiaGate, campaign finance, BidenGate.
Make the best possible cases, present a coherent case for the American people to easily understand, impeach in the House, and then make the same cases to the Senate.
if they lose in the Senate, America will watch Republican senators defend and acquit a traitor who sold out his country.
Then there will be a Blue electoral tidal wave in November 2020 to truly cleanse a filthy Trump and his Quislings from Washington.
And if there isn't, we as a country sadly deserve the Orange tinged fascist Russian puppet, with a strong taste for authoritarian dictators.
And maybe after seconds, we'll get a 3rd helping of that piece of shit.
God save America!
But first impeach Trump.
