Before shots fired in Alexandria interrupted all normal news, a story that was gaining interest involves the president’s reported comments at a meeting with Republican senators calling the House-passed American Health Care Act “mean” and a “son of a bitch.” Assuming he did not mean these words as complimentary, they were definitely embarrassing, given his stout support for and intensive lobbying on behalf of the self-same “mean son of a bitch” bill in the House.

But there is another possible explanation: Maybe the president has just been indulging his taste for polls. As two political scientists writing for the New York Times explain, the AHCA is not just unpopular nationally: It’s unpopular everywhere.

We found that Republicans have produced a rare unity among red and blue states: opposition to the A.H.C.A.

For example, even in the most supportive state, deep-red Oklahoma, we estimate that only about 38 percent of voters appear to support the law versus 45 percent who oppose. (Another 17 percent of Oklahomans say they have no opinion.) Across all the states that voted for President Trump last year, we estimate that support for the A.H.C.A. is rarely over 35 percent. A majority of Republican senators currently represent states where less than a third of the public supports the A.H.C.A.

Might this matter in 2018? The GOP senator thought to be most vulnerable, Dean Heller of Nevada, is from a state where the approval ratio for AHCA is a really dismal 28/53. Perhaps the second-most-vulnerable Republican senator, Jeff Flake, is a bit luckier: Arizonans only disapprove of AHCA by a net margin of 14 points. Given the evidence that support for Obamacare had a negative effect on Democrats running in 2010, some warning signs should be flashing for congressional Republicans generally.

And that brings us back to Trump’s comments and the really difficult political maneuver the GOP is trying to pull off in the Senate. Senators very much need their bill to be perceived as much less damaging to the American health-care system than the House bill. But at the same time, it needs to be close enough in reality to the House bill that the ultimate House-Senate conference product can still get through the lower chamber.

Presumably Trump is focused on the first task of suggesting — or pretending — there’s a world of difference between the two pieces of legislation. So maybe the leak of his derisive comments was intentional. But someone in the White House needs to be calling up key House Republicans to explain that this is all for show.
