"Impeachment comes up almost never," Doocy said in a phone interview Saturday when asked how often the topic comes up with voters in the Hawkeye State. "We sent all of our campaign embed reporters out with cameras to different campaign events and they all asked as many Iowans as they could, 'Will the impeachment process have any real bearing on who you're going to support?' And I think about one person out of 20 said that it would."

"They don't want to hear anything else about it," he added. "They want to hear about health care. They want to hear about immigration. They want to hear about their Social Security benefits more than impeachment."

An analysis of state polling last month found that the top issues among voters were health care, climate change and education, according to the Des Moines Register
