Just after the 2008 election, I was reading one of the conservative magazines. The editor in chief was trying to buck us up. He said, "Do not despair. For every action, there is an equal and opposite reaction. This applies to American politics as well." Hence, the birth of the Tea Parties.
Now, if the wounded democrats try outrageous things, they will have damaged their party permanently, and majorities will never vote for democrats again, ever. They can't be trusted to be honorable and grownup.
And then, the people of this country raise Hell like you've never seen.
