Since his inauguration, Trump’s support in every polled demographic has fallen. That includes groups where he had massive support (his own voters, evangelicals) and where he had very low support (Hillary voters, African-Americans). But there is only one group where his approval has fallen by a mere 1 point. What do you think that is? Christians? The wealthy? The South? Nope, nope, and nope.
Of course, Trump had low Jewish support initially. But those Jewish voters who care only about an aggressive, expansionist Israel love Donald Trump. If you were Jewish and a Trump supporter in 2016, you are still a Trump supporter. Which says a remarkable amount about a particular type of politics that makes you a stickier Trump supporter than literally every other demographic group in the nation.
And yet, among all religious groups, Jews still have the lowest overall Trump support, at 30 percent, although Trump now has a lower approval rating among atheists/agnostics, which he did not a year ago.
If you are a Republican, what should most freak you is the 10 point drop in the 30-44 age group, the 9 point drop among Midwesterners, and the 8 point drop among whites.
