In a demonstration of how the battle over health care is won or lost in the Senate, the RNC launches a new TV ad today that will air in Arkansas, Nevada and North Dakota targeting key senators with the message that America can't afford health care reform of the kind President Obama is proposing.

NARRATOR: "They've loaned Barack Obama their future, without even knowing it. Trillions for rushed government bailouts and takeovers, banks, the auto industry. The biggest spending spree in our nation's history. And they'll have to pay. The next big ticket item? A risky experiment with our health care. Barack Obama's massive spending experiment hasn't healed our economy. His new experiment risks their future and our health. The Republican National Committee is responsible for the content of this advertising."

The health care fight, then, gives us the peculiar situation of both national committees targeting some of the same senators. Last week, Organizing for America also launched TV ads in Arkansas and North Dakota, as well as Indiana, Ohio and Florida. But while OFA aims to sway both Republicans and Democrats, the RNC ads target only Democrats, namely Arkansas' Lincoln and Pryor, Budget Committee chair Kent Conrad of North Dakota, and Senate Majority Leader Harry Reid. Reid and Lincoln are both targets for Republicans in Senate races in 2010.

The visuals of the RNC ad -- full of children -- are in line with the party's renewed focus on America's fiscal situation. The Washington Post/ABC poll found today that Obama's most vulnerable issues appear to be his handling of the deficit, as well as health care.
