There is no reason that you guys cannot create a leadership caucus NOW.
Decide among yourselves who should be the nominee and announce which cabinet level position each of you will be willing to serve under your chosen leader.
You’re spending your constituencies donations on your petty little ad buys and debate scrimmages, knowing that all donations but one group will be flushed down an empty hole. While the Resident is following your debates around, getting free ads from network media everytime he tweets another dumb idea that he dreams up. If you stop the primaries now and begin the National Election – he will be caught off guard while impeachment related questions continue to be answered and you prosecute the election in chief.
