Democratic U.S. Senate hopeful Jacky Rosen will continue to remind voters of Senate Republicans’ attempts to repeal the Affordable Care Act last summer in her fourth television ad of the cycle that begins airing Thursday.

The 30-second spot, part of a new six-figure television buy, highlights the debate over the federal health-care law last year and stresses the freshman congresswoman’s support for fixing the Affordable Care Act rather than scrapping it entirely and starting anew. Though the ad does not mention her opponent, Republican U.S. Sen. Dean Heller by name, Rosen has been goading Heller on health care since she entered the race almost a year ago.

The ad features people holding up signs showing why they support fixes to the Affordable Care Act. One man holds a sign showing three dollar signs. A young woman holds up a sign saying that she has stage 4 cancer and could lose her health insurance. Others say “our kids,” “for my family” and “our son.”

“We all have reasons to fix our health-care system,” Rosen says.

In the ad, she says that Republicans “keep voting to repeal Obamacare instead of fixing it” and that Republicans want to end protections for pre-existing conditions and allow insurance companies to charge older people more for health insurance than younger people. She promises to “work with both parties to fix” the federal health-care law and lower costs.

A poll earlier this year from a pro-Affordable Care Act advocacy group found that 55 percent of respondents in Nevada support keeping the federal health-care law in place while making necessary fixes, while 40 percent support repealing it.

Rosen ran a similar ad in May acknowledging the “real problems” of the Affordable Care Act but urging people to work together to lower costs.
