No need. Even if all the Dems are voted out in November they can vote in another crook in their lame duck session.
There should not be a lame duck session, or at least lame ducks should not be able to vote in it. Fear of not being re-elected is the only thing that might cause a Congressman to consider the wishes of his constituents; once this is removed, so is any incentive to represent the people. Nothing left but using votes to return favors or reward cronies, and other forms of corruption.
