After three years of trying unsuccessfully to delegitimize President Trump and overturn the result of the 2016 presidential election and then holding the threat of impeachment over his head to undermine his presidency, House Democrats have decided that they’re actually going to try to impeach Trump.

First, it was Trump’s joke about Russia finding Hillary’s emails, then Stormy Daniels, then James Comey’s firing, Robert Mueller, two years of Russiagate — on and on and on. Every one of them was supposed to be an impeachable crime, and every one turned out to be a nothingburger.
