The N.Y. Times' Alex Burns and Jonathan Martin have an early warning for the GOP, from their reporting in Alpharetta, Ga.: "Suburban G.O.P. Voters Sour on Party, Raising Republican Fears for 2018."
The takeaway: "Interviews with Republican-leaning voters in four suburban districts — in Georgia, Kansas, Minnesota and New Jersey — revealed a sour outlook on the party. These voters, mainly white professionals, say they expected far more in the way of results by now."
Why it matters: "Should Republican voters remain so demoralized — and Democrats so fired up — it could imperil dozens of congressional seats that are usually safe."
