Waters was probably hoping the house would fall back into dem control again...she probably though Pelosi was reading the correct tea leaves...I guess not..
At worse she will be censured and lose ranking which in her mind she will wear as a badge of honor..
That's what I was thinking too. Poker players would call it a "tell" - Waters has lost confidence in the election cycle and would rather deal with the current Congress than the next.
She probably doubts a Presidential pardon will be available after January, too...
