The Democrats should reduce their message to impeachment only. The House should curtail investigation of his tax returns to 2017 and 2018. Impeachable offenses cannot be found in prior years. I would bet that if the House reduced their demand to only 17 and 18, he would poop his pants.
We should shut down all investigations, e.g, stuff from before his presidency, that in their natures can’t reveal impeachable offences. We should try to wait to take action to maximize the publics’ being onboard to increase the unlikely possibility that the Senate will go along. Notwithstanding, he must be impeached. We can’t wait until it’s too late to act. Even without public support and guaranteed failure in the Senate, he must be impeached!
Mueller sent the message that his report as delivered was sufficient. That’s why he gave the narrowly drawn thanks to Barr for releasing what he released. Some investigations may be helpful, but holding up the show for redactions is unnecessary and impeachment stopping. And as they say, without spelling out how, impeachment opens up the availability of investigation resources.
If investigations were strictly limited only to ones that the public can easily imagine to reveal impeachable offenses, they would be able to focus on the main and only point. Trump would go nuts.
