It is not about whether she is doing the right thing or not. It is just that she is right about the current situation. There are far more Democratic Representatives that would not vote this month.
It is just math. It is stupid of these centrist Democrats to cry about it and make it a scene in public. They could have stayed quiet and said they wished Pelosi would bring it up for a vote this month if asked. Instead, they made it a public fight. Now, they will be asked more questions by reporters and others. It is stupid politics on their part.
