The Republicans are within arm’s reach of the 218 seats needed to control the House of Representatives, so while the counting continues, let’s take a look at some of the key contests to keep an eye on.

In Ohio’s 9th congressional district, Democratic incumbent Marcy Kaptur had a narrow lead over Republican Derek Merrin.

In Arizona’s 6th district, the margin is razor-thin between incumbent Republican Juan Ciscomani and his Democratic challenger Kirsten Engel, with just 200 votes separating them – Engel is in the lead.

In California’s 13th district, Democrat Adam Gray is hoping to unseat incumbent Republican John Duarte, who is currently ahead in the count.

Likewise in California’s 22nd, 27th, 41st and 45th districts where the races are tight, but tallies suggest Republicans will keep their seats, while in the 9th district, Democrat Josh Harder is holding on against Republican Kevin Lincoln.

In Colorado’s 8th district, Democrat Yadira Caraveo is holding on against Republican challenger Gabe Evans.

In Oregon’s 5th district, Democrat Janelle Bynum may unseat incumbent Republican Lori Chavez-DeRemer.

In Iowa’s 1st district, Republican Mariannette Miller-Meeks is clinging on by 0.2 percentage points over the Democrat’s Christina Bohannan.

Republicans have already won the Senate and the White House so winning control of the House could give President-elect Donald Trump significant power to carry out his political agenda.
