You talked politics with your mother, brother, bartender and banker, and all it did was jack up your blood pressure.

You know that you are not alone. In this divisive period in American politics, two professors in Nebraska and one in California decided to conduct a survey in March 2017 to see how pervasive were high stress, conflict with family and friends, and even health problems related to thinking and talking about politics.

The three — Kevin Smith and John Hibbing, political science professors at the University of Nebraska-Lincoln, and Hibbing’s son, Matthew, an associate professor at the University of California, Merced — wrote a paper on their findings last year. They expect it to be published in a journal this year.

Among many findings:

  • 38% said politics has caused them to be stressed.
  • 31.8% said exposure to media outlets promoting a contrary view “can drive me crazy.”
  • 29.3% said they had lost their temper because of politics.
  • 25.6% said they spend more time thinking about politics than they want to.
  • 23.3% said politics compelled them to think seriously about moving.
  • 16.9% said politics has created problems for them in their extended families.
  • 16.6% said politics at times has made their home life less pleasant.

About 800 people took the survey through YouGov, a polling firm that recruited a demographically representative sample of American adults for the survey.

John Hibbing said some people have expressed surprise that the findings weren’t more dramatic.

“Sometimes, people are reluctant to ’fess up to things” like stress and conflict, he said. Also, “We have to remember that a lot of people just don’t care about politics.”

Hibbing hopes to continue the survey through the years to make comparisons. The survey report says: “It may be that the costs of politics were unusually acute when this survey was administered, just two months after the inauguration of an extremely polarizing president.” On the other hand, the report says, the presidencies of George W. Bush and Barack Obama were labeled by some as “the most polarizing ever.”

Larry Kavich, a retired Omaha businessman who splits time between Omaha and Arizona, said he had regularly eaten Friday lunch with two friends at the Arizona Bread Company in Scottsdale. But the day after Trump was sworn in, one of the men derided Kavich for supporting Trump.

“How could you support that blah-blah-blah?” the friend asked.

“I walked away and said, ‘He’s not worthy of my friendship,’ ” Kavich said. He hasn’t spent time with that man since, but he has with the other friend in the group.

Kavich, 74, said he has felt compelled to remove the Trump-Pence bumper sticker from his car because of the looks he receives. “I have a MAGA (Make America Great Again) hat and would not wear it out here in Arizona. I wouldn’t wear it anywhere. There are too many wackos out there.”

Mary McNamee, a retired nurse educator and administrator at the University of Nebraska Medical Center, said she and some of her acquaintances stay away from discussions of politics. “We’re going to avoid that topic,” said McNamee, 74, who volunteered for the Hillary Clinton campaign. These are hard times, she said, and people need to think about how to get along.

Watching news on television all day can be upsetting, she said.

“You make it much worse by hearing it over and over and over again,” she said.

As she spoke, she visited a 95-year-old aunt in New Orleans who was constantly dialed in to Fox News. McNamee said she, her husband, sister and aunt would leave politics alone on this visit.

Ellen Shively, 64, married Jerry Wissing in October, and they knew that they held opposite political perspectives. Like McNamee, Shively said she and her husband have decided to remove politics as a routine topic of conversation. Shively, a graphic designer and a liberal Democrat, said that when politics comes up, anger can follow.

Wissing, 65, agreed that politics is touchy between him and his wife. He supports Trump. “What I always say is, ‘Let’s just wait and see what happens,’ ” he said.

“There’s so many things in life to have stress about,” said Wissing, a software developer. “You can’t let things that you can’t control cause stress in your life.

Shively said she and her husband try to give each other plenty of space when it comes to politics.

“We just stay away from it,” Shively said. “The only thing I can say is the president stresses me out.”
