One big problem with his "stupid" statement is that the American public have never been stupid enough to give ObamaCare majority approval. According to Gallup, the highest approval in their polling since December of 2012 was 48%. Today, it sits at a freshly-printed record low of 37%.
Polls conducted by Business Insider, going all the way back to 2009, showed that no-higher that 40% have ever thought ObamaCare was good for the country.
