Democratic Rep. Tom O’Halleran fended off a challenge from Republican Wendy Rogers in Arizona’s 1st Congressional District, which President Trump carried by one point in 2016.

O’Halleran cited his membership in the bipartisan House Freedom Caucus as evidence that he would work across the aisle, while Rogers played up her support for Trump in the northeast Arizona district where many rural voters supported the president in 2016. Her low-profile campaign made the race much more competitive than many Republicans expected.
