It’s important to remember, when considering the Republican plan to overhaul Obamacare, that the only constituency that fervently supports throwing out the Affordable Care Act is Republicans. In the most recent Post-ABC News poll, three-quarters of Republicans supported repealing Obamacare, sure — but 9 in 10 Democrats and two-thirds of independents favored strengthening the existing law. The net effect, then, is that Republicans on Capitol Hill are trying to deliver a long-held promise to their base — while not alienating other voters who might come to the polls next fall.
