“I take insulin and 12 other medications, and my daughter’s medicine costs $700 a month. We couldn’t afford it without healthcare reform,” Diane, from Denver, says in the video.

A chorus of voices demands at the end of the video: “Don’t let insurance companies do whatever they want — drop my coverage, deny my care, raise my costs.”

Just a sample of the real people who can't go back to the way the health insurance industry worked before Obamacare. They appear in a web ad the Democratic Congressional Campaign Committee is running in 44 competitive House districts.

House Republicans have voted nearly 50 times to repeal the Affordable Care Act, which would raise prescription drug costs for millions of seniors, allow insurance companies to deny coverage to 129 million Americans with preexisting conditions - including 17 million children - and to increase costs on middle class families.

"For every statistic, there are millions of seniors who are saving thousands on prescription drugs, countless Americans who won't face bankruptcy because of health care, and millions of sick kids who are guaranteed coverage -- and those are the people Republicans are hurting with their obsessive repeal efforts," said Emily Bittner of the Democratic Congressional Campaign Committee. "Not only would Republicans' repeal hurt millions of middle class Americans, they refuse to put forward an agenda to solve these problems. The Republican repeal takes away coverage, hikes rates, and sends too many Americans back into a broken system where insurance companies were free to do whatever they wanted, at the cost of middle class families. The costs of Republican repeal are simply too high -- and these are the faces of those who will hurt the most."
