“Actually we do. Without the formal paperwork, “impeachment” simply does not exist as far as the Senate is concerned.”
So then the House Democrats can create an ‘impeachment investigation’ and dress it up like an impeachment without regard to ANY recognized rules, but Senate Republicans have to adhere to what was done the last time (Clinton). Sorry, that’s playing their game. If they issue a fake impeachment and then sit on it, we can & should throw it right back at them without waiting. Give them a deadline to submit or we vote to dismiss.
No, it is the exact opposite of "playing their game"..it is adhering to the Constitution instead of making it up as we go. And the public at large sees and understands that, given that public support for impeachment has gone down and hard support for Trump has gone up as a result of their shenanigans.
When your enemy is busily shooting himself in the foot, you do NOT take his gun away. They look more ridiculous every single day.
