[....] The opposition party needs to win 24 seats to take control of the House in 2018. Understandably, operatives and handicappers have focused on the 23 districts that Republicans hold, which voted for Hillary Clinton last year. But some of the incumbents are very popular, with brands that are distinct from Trump’s, and they are unlikely to lose no matter how bad the headwinds become. [....]

Third Way did a deep dive to try to understand what the 2018 playing field will look like. The center-left think tank focused on 65 “Majority Makers,” the battlegrounds where a majority would most likely be won. Using 48 Census data points, two experts from the moderate group looked at variables such as how many people moved into a district over the past year, what percentage of residents have access to broadband Internet and how many houses are vacant.

The numbers underscore how different even the 23 GOP-held Clinton districts are demographically. Many are suburban and overwhelmingly white. Others are rural and heavily Latino. Within the broad categories, there are stark differences on income, educational attainment and employment rates. More than half of adults in New Jersey’s 7th District, for example, graduated from college. Only 17 percent in California’s 10th District did.

“The most important takeaway is that there is no one kind of voter or district that can deliver the House for Democrats in 2018,” said Lanae Erickson Hatalsky, the vice president for social policy and politics at Third Way. “There’s been a lot of focus on suburban districts. There’s no doubt that those are important, but there are not enough of them to win the House.” [....]

“You can’t get to a House majority without winning over Trump voters,” she said. “There are some people who definitely want to believe that they can because they still don’t know how to deal with Trump voters and are intimidated by the idea of appealing to them.” [....]
