If the Dems (and Repubs for that matter) can't do their duty to uphold the Constitution, then America is done. This is the time when it matters, not some theoretical election over a year away. And if you think the GOP/Trump is going to attempt a coup after the election, then it is definitely the time to act now to establish the rights, responsibilities, and authority of Congress.
