They have all the facts over at the Cedar Rapids Gazette:
"The House passed the American Health Care Act, HR 1628, on May 4, 2017. That legislation, a plan to repeal and replace Obamacare, would have allowed insurers to set premiums based on a patient’s health status if that patient had let his or her coverage lapse, the Congressional Budget Office reported.
“Community-rated premiums would rise over time, and people who are less healthy (including those with preexisting or newly acquired medical conditions) would ultimately be unable to purchase comprehensive nongroup health insurance at premiums comparable to those under current law ...” the office determined.
Ernst was among 51 Senate Republicans who voted July 25, 2017, to begin debate on the House-passed legislation.
The Senate GOP ultimately couldn’t get enough of its members to sign on the repeal, even when the caucus stripped it down to a “skinny” version that reduced insurers’ ability to block consumers with preexisting conditions. Ernst was one of 49 Republicans who voted for the skinny repeal July 28, 2017."
