Since Johnson took office you've passed more laws than he has. If you call an election you risk GIVING the Tories power.
You also risk repeating the democratic failure of 2017 where the majority vote for anti-no-deal parties but no-deal parties get more seats.
The logical way to decide between them is a referendum.
The Tories are calling you a coward for not calling an election... True cowardice would be to let their taunting manipulate your pride.
Now is when MPs from ALL parties should work together. Every MP who sees what a disaster No-Deal is for the people you have a duty to protect should be coming together in a temp government, not retreating to away weekends with the members.
