If there were "overwhelming evidence" then Trump would be in jail. Obama and the Democrats used the IRS like a weapon to go after their enemies, to a degree that would have made serial IRS abusers like JFK and Nixon blush. Did they go after Trump and find nothing? Or did they just underestimate him so much that they didn't bother? In Canada, if you cheat on your taxes, you are investigated by the CRA. The same would apply in the US with the IRS. Did the IRS investigate him? If the evidence that the NYT claims is "overwhelming" exists, then why isn't he in jail? This just doesn't add up, at all.
As for focusing on beating Trump in 2020, those aren't my words. That's what Adam Schiff and Nanci Pelosi are saying. Did you not watch the Adam Schiff youtube I posted? You should. He's smart. He knows trying to impeach Trump would be a disaster for the Dems. They'd lose, and make Trump an even bigger symbol for Americans wanting to fight the system. It's a losers' game. It won't work. Which is why careful attention should be paid to those Dems screaming for impeachment. These are the real enemies of the Democrats.
