Truth.
Though I doubt they realized that when they wrote it...but it's true. Any of his constituents that aren't in a labor union can just go pound sand.
Nothing about this from the major media outlets...
Update: This morning, the Twitterverse is saying that reports of Tim Cullen's return have been "refuted." He now exists in a quantum state between Illinois and Wisconsin. If you're someone who can actually communicate with him - such as liberal reporters, union bosses, and whoever stocks the mini-bar at his undisclosed location - please tell him his taxpaying constituents would like to know where he is, and whether he plans to return to his job any time soon.
Cut off his phone, and cut the electricity in his office to reduce costs. Delay his pay while you calculate it by hand. Move his parking space way out. Audit his travel vouchers. Be sure his staff members are not being used for "personal" duties. Be sure he has not accepted any "incentives" or payola from lobbiests. Just for starters.
He should either return or petition for political asylum.
