爱荷华州选民将于周二选出该州下一任联邦参议员，两届现任参议员乔尼·恩斯特（共和党）不再寻求连任。
Iowa voters choose their next U.S. senator on Tuesday with two-term incumbent Sen. Joni Ernst (R) retiring.
共和党提名联邦众议员阿什利·欣森（共和党）竞选，力求在通常倾向共和党的“鹰眼州”守住该参议院席位。
Republicans are seeking to hold the Senate seat in the usually red Hawkeye State with U.S. Rep. Ashley Hinson (R) as their nominee.
欣森是三届众议员，在共和党初选中以近50个百分点的优势击败前州参议员吉姆·卡林。
Hinson, a three-term representative, defeated former state Sen. Jim Carlin by nearly 50 points in the GOP primary.
她获得特朗普总统、爱荷华州两位参议员以及共和党建制派大多的支持。
She has the backing of President Trump, both of Iowa's senators and much of the Republican establishment.
虽然共和党在鹰眼州已把持十余年，但民主党对本轮选举感到乐观，认为全国政治环境似乎正向有利于他们的方向发展。
While Republicans have had a stranglehold on the Hawkeye State for more than a decade, Democrats are feeling optimistic this cycle with the national political environment seemingly trending in their direction.
民主党参议员提名人是州众议员乔什·图雷克，他是一名残奥会运动员，已对欣森展开强有力的竞选。
Their Senate nominee is state Rep. Josh Turek, a Paralympian who has run a robust campaign against Hinson.
图雷克在民主党初选中以约36个百分点的优势击败州参议员扎克·沃尔斯。
Turek defeated state Sen. Zach Wahls in the Democratic primary by about 36 points.
上一位在联邦参议院代表鹰眼州的民主党人是汤姆·哈金，他于2015年退休，由恩斯特继任，恩斯特最近一次当选是在2008年。投票将于美东时间晚上9点截止。
The last Democrat to represent the Hawkeye State in the U.S. Senate was Tom Harkin, who retired in 2015, when he was succeeded by Ernst, who last won in 2008. Polls close at 9 p.m. EST.
