(CNN) - The health care ad wars aren't letting up as the dog days of summer set in.
First, national Republicans are targeting two potentially vulnerable 'Blue Dog' Democrats during the congressional recess over Democratic efforts at health care reform.
The new ads launching Friday will air in the swing districts of New York Rep. Mike Arcuri and Ohio Rep. Zack Space. NRCC spokesman Ken Spain declined to reveal the size of the ad buy but described it as "significant."
"President Obama and Nancy Pelosi are cooking up a risky experiment, on health care. Higher costs, tax hikes, and, get this, massive cuts to Medicare," versions of both ads state. Arcuri/Space already votes with Pelosi 90 percent of the time, now what do you think he'll do?"
Meanwhile, the liberal labor group Americans United for Change announced Friday it is launching a new ad on national cable next week that beats back at debunked claims about the Democrats' health care plans and spotlights what it calls "the real death panels that exist in America today."
"Their lies about phony Death Panels have all been proven false...unfortunately, there are real death panels in America," the announcer says, as footage is shown of 13-year old congressional testimony from a former Blue Cross/Blue Shield medical director who said she has denied patients potential life-saving surgeries.
