Moff Jerjerrod: The Emperor's coming here? Darth Vader: That is correct, Commander. And, he is most displeased with your apparent lack of progress. Moff Jerjerrod: We shall double our efforts. Darth Vader: I hope so, Commander, for your sake. The Emperor is not as forgiving as I am.

There was a disturbance in the Force on Capitol Hill Thursday afternoon.

At least for Democrats.

It's one thing for House Minority Leader Nancy Pelosi (D-CA) and Senate Majority Leader Harry Reid (D-NV) to tangle with the likes of House Speaker John Boehner (R-OH) and Senate Minority Leader Mitch McConnell (R-KY). Boehner and McConnell are the Democrats' traditional adversaries. For Democrats, they're just on the "Darth Vader" level.

But it's an altogether different enterprise for the man who Democrats view as the GOP's "Emperor" to swing by.
