Here's a rarity for a House Democrat facing a competitive race this fall--a campaign ad touting the attributes of the recently-enacted healthcare law.

A new 30-second spot from Rep. Scott Murphy (D-N.Y.) focuses on some of the law's more politically palatable provisions and hits Republican challenger Chris Gibson for advocating healthcare repeal.  

"Time for a reality check," the ad's narrator says. "Chris Gibson wants to repeal the healthcare law. Chris Gibson would let insurance companies go back to denying coverage for preexisting conditions. He would let them restore limits on lifetime coverage."

The messaging marks a break from many endangered Democrats across the country who are touting their votes against the healthcare law in campaign ads. 

A recent spot from the campaign of Rep. Bobby Bright (D-Ala.) highlighted his vote against "massive government healthcare." 

Election handicapper Charlie Cook has Murphy's race in the "lean Democratic" column, but the conservative group American Crossroads announced Wednesday it plans to start spending against Murphy. The National Republican Congressional Committee has already spent more than $450,000 in IE money targeting the incumbent.   

Murphy isn't the only Democrat who has engaged on healthcare this fall. Rep. Earl Pomeroy (D-N.D.) and Sen. Russ Feingold (D-Wis.) used their support for the law to attack their Republican opponents for, they said, standing with insurance companies.
