[...] it has frustrated many of MacArthur's fellow moderates, who complain that the latest repeal iteration would hurt people with pre-existing conditions and deny basic services like maternity and newborn care. The campaign arm for House Democrats boasts that MacArthur's efforts have been a great recruiting tool in its efforts to take the district in next year's midterm elections. Under his measure, states could get federal waivers to the requirement that insurers charge healthy and sick customers the same premiums and that they cover specified services like preventive care and wellness visits. Some members have expressed concerns that the bill now will allow states to approve waivers that would make it more expensive for people with pre-existing conditions to obtain health insurance. "It doesn't allow a state to do anything with premiums based on health status unless they've created a fund to help those very people," MacArthur said. [...] to help the states start them, we have a $130 billion patient stability fund, which is part of the bill. Fifteen billion is targeted just for mental health care and maternity, but the other $115 billion is all available to help the states create these very kinds of pools and make them successful. The Democratic Congressional Campaign Committee recently took out digital ads targeting 30 Republican-held seats on the health care proposal.
