He (and Pelosi) don't care how many of us they lose or how frustrated we are about all the "change" that is destroying our nation on a daily basis. It's been written elsewhere he figures he's a one term president and all he wants to do is gut our lives as we know them and get his agenda adopted in its entirety. It's his legacy and he wants to do as much as possible, as soon as possible - thus everything is URGENT to Pelosi and him. If all dems are kicked out of office afterwards (and if they pass Obamacare, it;s likely they will be), it's no skin off their backs and victory in having substantially changed America for their own ends and purposes.
