In the Republican-leaning California 48th Congressional District in Orange County, Republican challenger Michelle Steel has talked about taxes, while Rouda has focused on health care and prescription drug costs.
The pattern is similar outside Philadelphia, where GOP Rep. Brian Fitzpatrick accuses Democratic challenger Christina Finelo of supporting police defunding.
Wagner has voted for bills that would have ended the coverage that former President Barack Obamaโs health care law guarantees people with preexisting conditions.
Freitas has said he thinks government intrusion into health care doesn't help.
Democrats have run health care themed ads against Republicans in numerous states including Colorado, Illinois, Indiana, Nebraska and Texas.
