For some time, I've been arguing that the GOP should have had a plan to repeal ObamaCare ready - and on the President's desk - the week that Donald Trump took office. The ACA's elimination should have been a day one priority, then you could rest of the year working on healthcare fixes and tax reform. I've heard a whole pile of excuses about why that didn't happen and I've never really bought any of them.
There were only two answers that made sense: Either the GOP didn't really want to repeal ObamaCare, or they simply dropped the ball and we're witnessing one of history's worst cases of political shortsightedness.
While I still suspect there are a lot of Republicans who'd love nothing more than to leave the ACA in place and have the whole issue go away, it sounds more like the GOP just ...failed. According to Pat Toomey (R-PA), no one bothered to ready an ObamaCare repeal bill, because they all thought Hillary was going to be your next President.
