a plurality of Democrats believe, accurately, that more Americans have health insurance, while a plurality of Republicans believe the opposite. A clear majority (61%) of voters who backed Hillary Clinton answered the question correctly, while an even larger majority (74%) of voters who backed Donald Trump got it wrong.
The persistence of the “reality gap” continues to be a problem.
A national Public Policy Polling survey found Trump voters believing all sorts of wrong things, on issues ranging from unemployment (Trump voters believe it went up under Obama, which is the opposite of the truth), to the stock market (Trump voters believe it went down under Obama, which is the opposite of the truth), to the popular vote (Trump voters believe it went in the Republican’s favor, which is the opposite of the truth). the “reality gap” isn’t altogether new: for years, many Republicans have told pollsters they believe border security has weakened under Obama (it’s actually strengthened), the deficit has gotten bigger (it’s actually shrunk by a huge margin), and the nation’s uninsured rate has gone up (it’s actually at an all-time low).
