they will not,why I do not understand
They won't because they are risk averse and scared. They think if they make zero mistakes from now on they may hold on and win. It's a cowardly strategy and a similar one almost lost the election for them in 2000 against a dopey Al Gore.
They need to act as if they have already lost and have nothing more to lose. Shake some things up and start launching hail mary's.
