The super PAC aligned with House Speaker Paul Ryan, R-Wis., has opened five more field offices in threatened districts as the Republicans build fortifications against a possible midterm tsunami.

Congressional Leadership Fund has put boots on the ground in Maine’s 2nd Congressional District, North Carolina’s 13th District, Ohio’s 1st District, Pennsylvania’s 17th District, and Washington’s 8th District. The Pennsylvania seat is new, the other four established districts have a history of voting Republican, and three supported President Trump by comfortable margins in 2016.
