....the attempt is sufficient for criminal charges IF he could be charged
If that were true, Pelosi would jump on the band wagon for impeachment. Sorry, your facts are wishful thinking at best.
The facts are, Trump was the object of an attempt to remove him from office, that failed miserably.
Trump will win again in 2020. Biden will divide the party between establishment Democrats and the hard core supporters of Bernie, just like Hillary did. And, if Biden gets the nomination, many Bernie supporters will not vote in the coming presidential election, like they did not do the last presidential election.
The Democrats are screwed. They just can not seem to stop eating their own, such as they did Franken and other members of their party.
