FFS. This national referendum already happened in 2012.

Results:

1) Romney, who ran on repealing the ACA, lost the election. He lost both the popular vote and in the electoral college. Mr. ‘47%’ got 47% of the popular vote, which, in case you missed it, is a losing margin.

2) In 2012, the GOP lost seats in the house. In fact, the only reason the GOP kept control of the House is the gerrymandering they did in 2010. 2 million more votes were cast for (D) representative than for (R) representatives in 2012.

So we have effectively had at least two recent national referendums on the subject of the ACA, and it was supported in both cases.
