IOWA CITY, Iowa (AP) — Iowa officials have certified a Republican candidate as a six-vote winner for an open seat in the U.S. House, in what is shaping up to be the closest congressional election in decades. Republican Mariannette Miller-Meeks finished ahead of Democrat Rita Hart in Iowa’s 2nd Congressional District after a recount saw her 47-vote lead steadily dwindle to single digits.

The state Board of Canvass voted Monday afternoon to certify Miller-Meeks as the winner over Hart by a final count of 196,964 to 196,958. The board also certified President Donald Trump as the winner of the state’s six electoral votes.
