A very effective ad being run in Colorado by Udall...

against Cory Gardner.

It points out that Gardner voted for tax breaks for companies to ship their jobs overseas. I've noticed that Alison Lundergan-Grimes is running a similar ad in Kentucky.

But that is one issue that is hard for the Republicans to rebut. And nearly everyone of the Repubs have voted for these taxcuts. It gets right to the heart of the matter, in my opinion.
