t is hard to overestimate the damage the Freedom Caucus has done to the fledgling presidency of Donald Trump, and to the country. By blocking the American Health Care Act of 2017, the conservative group has guaranteed that Americans will struggle forward under the burden of Obamacare. In the next few months insurers will announce their premium hikes for the coming year; chances are, given the continuing withdrawal of major companies from the marketplaces and the ongoing failure of the bill to attract enough young and healthy participants, the new rates will not be pretty. Last year premiums went up 25%; it’s likely the increases will be higher this year.Republicans will own those higher rates. Their failure to repeal the financial underpinnings of Obamacare and start replacing that failing program with an approach that encourages competition and that embodies numerous other common sense reforms will mean that families hit by ever-higher costs will blame the GOP. Voters elected Donald Trump and a GOP Congress to get this job done – the number one promise of every Republican campaign since 2010.
