Is Obamacare losing steam as campaign material for Republicans in key Senate races? A new analysis shows a sharp drop in its use in TV ads, including in Arkansas. No wonder. Hard to argue with the positive results of the Affordable Care Act — millions enrolled, a halt in health care cost increases, a reduction in hospital charity costs and more.

From a Talking Points Memo account of the Bloomberg analysis:

In North Carolina, Obamacare was mentioned in 54 percent of issue ads in April; it fell to 27 percent in July, per data from Kantar Media’s Campaign Media Analysis Group.

In Louisiana, Obamacare fell to 41 percent of top five issue ads in July; in Arkansas it dropped to 23 percent, according to CMAG. The issue dominated the airwaves in both states in April.

Of course, in Arkansas, if you merely edit out the letters “care” you still have a potent campaign issue.
