It's a short but big week in Washington as Congress returns from two weeks of recess. The Senate convenes Monday afternoon and the House doesn't wander in until Tuesday, when they'll face a potential government shutdown at the end of the week. We've been here before, way too many times, but now there's an entirely new dynamic—a White House that is making the shutdown threats and throwing the process into total chaos as they keep throwing in new issues to muck things up. Democrats have made their demands—funding for Obamacare's cost sharing repayments to keep the marketplace stable, permanent funding for retired coal miners' health benefits, and no border wall.
