Shortly before the May 3 Indiana primary, a video of a Donald Trump supporter accosting Ted Cruz went viral. Surrounded by a throng of Trump fans shouting “career politicians have killed America,” the Texas senator tried to engage the man in a mock debate—without much success. Mr. Cruz made several attempts to discuss Mr. Trump’s record, then finally gave up and told the man that Mr. Trump “is playing you for a chump,” adding: “Ask yourself . . . why the mainstream media wants Donald Trump so desperately to be the Republican nominee?” The Trump supporter—whose favored candidate reportedly has enjoyed $2 billion in free media coverage—replied: “They’ve backed you every chance they get.”

Episodes like that, combined with Mr. Trump’s romp through the Republican presidential primary season, have shaken many people’s faith in the American electorate. But what if Trump voters, however uninformed, are still making a rational decision by backing him?

That is the contrarian argument advanced by political scientist Samuel L. Popkin of the University of California, San Diego, who has studied public opinion and elections for half a century. A native of Superior, Wis., the 73-year-old Mr. Popkin has also served as a consultant for the presidential campaigns of George McGovern, Jimmy Carter, Bill Clinton and Al Gore. Mr. Popkin is perhaps best known for applying the rational-choice theory of economics to voting.

His seminal 1991 book “The Reasoning Voter” argues that voters are public investors who “expend effort voting in the expectation of gaining future satisfaction.” They “combine, in an economical way, learning and information from past experiences, daily life, the media, and political campaigns” to make reasoned judgments about politicians.

One of Mr. Popkin’s favorite examples of how “low-information voters” use “cues” to form logical conclusions is Gerald Ford’s eating an unshucked tamale, which signaled to many Latino voters that the president didn’t understand their culture. History repeated as farce this week when Mr. Trump on Cinco de Mayo tweeted a photo of himself eating a taco bowl: “The best taco bowls are made in Trump Tower Grill. I love Hispanics!”

Mr. Popkin, who was in New York City visiting family, sat down to talk on Wednesday afternoon, interpreting the often bizarre-seeming Republican primary season by using his political theory of low-information rational voting. CONTINUE AT SITE
