The National Republican Congressional Committee today begin airing radio ads attacking House Democrats in swing districts, including U.S. Reps. Rick Nolan and Tim Walz, for refusing to defund the Affordable Care Act

Republicans aim to frame the federal government shutdown around President Obama's health care reform law, also known as Obamacare.

And Walz, Nolan and eight other Democrats are among the targets. The NRCC did not indicate the size of the ad buy or how often they'll run.

"How out-of-touch is Tim Walz with Minnesota families? So out-of-touch that she voted to shut down the government in order to protect Congress' taxpayer funded healthcare!" the start of the script for the Walz ad reads.

An identical script will run on ads criticizing Nolan.

Despite the shutdown, the online insurance marketplaces for the Affordable Care Act debuted Tuesday, albeit with glitches.

The Democratic Congressional Campaign Committee also went on the offensive this week, running automated telephone calls targeting 63 House Republicans over the budget crisis, including Reps. John Kline and Erik Paulsen.

The script from the Kline's call reads:

"While you were sleeping Congressman John Kline shut down the government. You heard that right. But even worse – Congressman Kline is still getting paid – and he's not listening to our frustration. All because of his demand to take away your benefits and protect insurance company profits."

The script reads the same for Paulsen, but technically he and Kline are not getting paid during the shutdown. They've requested that their pay be withheld until it ends.
