If control of the House of Representatives flips to the Republicans this fall, economist Jim Doti believes he found the issue driving political change: the gas pump.

Chapman University’s veteran economic forecaster was trying to see which historic economic, demographic or voting patterns factors might provide numerical hints for November’s midterm elections in which control of the House is at stake.

Doti’s formula suggests Republicans will gain control of the House by flipping 53 of the legislative body’s 435 seats to the GOP side of the political aisle in November. The flip isn’t terribly stunning, considering the party controlling the White House has lost an average 27 seats in midterms since World War II. And over the Fourth of July weekend, forecasters at fivethirtyeight.com gave the GOP an 87% chance of winning the House in the first fall projection for 2022.

Political track records are not foolproof prognostications of future election results. But Doti was startled to discover the pivotal vote-changer that’s bad news for President Joe Biden and his Democrats: record-high gasoline prices.

“First of all, let me say that this was a big surprise to me,” Doti says.

Price points

Pain at the pump was not on Doti’s mind when he started the research with fellow Chapman professor Fadel Lawandy. He was betting big vote swings followed inflation, which in 2022 is running at 40-year highs.

But when the professors looked at voting patterns versus traditional measures of the cost of living, such as the consumer price index, Doti said, “I found nothing, even when you look at some of our high inflationary periods.”

So gasoline prices were input into his formula, and to the professors’ astonishment, fuel inflation was a significant political driver. The out-of-power party gained more House midterm seats when gasoline was pricier.

Equally noteworthy were the only two times the party in the White House grew its political base in the House at the midterms — Bill Clinton’s second term (1998) and George W. Bush’s first term (2002).

Gas prices were falling in both of those outlier periods.

So why is gasoline — a relatively modest expense for many Americans — such a political flashpoint? It’s the simplicity of the economic measurement.

“People every week fill the tank. They see these big prices,” Doti says. “It’s not like reading the CPI. Or reading the Wall Street Journal. It’s affecting their pocketbook, and they get it. They’re agitated.”

Bad start

Biden’s unpopularity doesn’t help. The president scored a low approval rate of 41% in May, according to Gallup. That compares with an average of 51% at the same moment for presidents since World War II. The Chapman formula says that adds up to nine more lost Democratic seats.

Yes, there’s decent economic growth — Biden’s 2.8% gross domestic product expansion is better than the 2.5% post-WWII average. But that earns Democrats only one seat by this math.

And a Republican winning Virginia’s governorship — an election that’s proved to be a leading indicator of political fortunes — translates to a six-seat House pickup for the Republicans, says the formula.

Then ponder gas prices — up 61% in a year versus average hikes of 2.5% annually. That pump pain is worth 29 seats for the Republicans — giving them the House if this Chapman forecast is correct.

You don’t need an economics doctorate to understand that if folks vote with their wallets, gas prices are an obvious winner for Republicans. And a psychology degree isn’t required to comprehend the emotional response gas prices can create — and voters often act with their hearts.

To me, though, what will be intriguing to watch is what voters think this fall about topics hard to quantify. The Supreme Court’s actions on reproductive rights or gun control. Or the hearings into the Jan. 6, 2021, insurgency.

I’ll note that 1974’s midterms — when the Republicans controlled the White House and lost 48 House seats — were the party’s second-worst outcome since World War II. By the way, the 50 seats lost in Dwight Eisenhower’s second term in 1958 was the GOP’s biggest drop.

What was up in 1974?

Gas prices jumped 33% to 53 cents per gallon. Inflation ran at 11%. But Richard Nixon also resigned from the presidency. Oh, and it was the first midterm election after the Supreme Court made abortion a right in every state in Roe v. Wade.

Sketchy tale

Doti tells the tale of a recent visit to a Chapman University graphic design class.

Students were assigned to draw a political cartoon. Doti was there to provide some economic background highlighting the nation’s inflation challenges.

And what was the theme of the graphic design professor’s favorite cartoon from the assignment? A humorous sketch of a gas station where the price was artfully displayed at $18.89 a gallon.

“That brings home the fact people see it, it’s transparent,” Doti says of the fuel pump’s political power. “The analysis clearly shows gas prices affect how people vote in midterm elections — but not the overall trend in consumer prices.”

‘Real’ results

I wondered if real estate also mattered, politically speaking.

So I loaded my trusty spreadsheet with a U.S. price history dating to 1953 from dqydj.com. Tracking the past 17 midterms with math far simpler than Doti’s analysis, one trend stood out as I eyeballed swings in “real” home prices in the 12 months preceding a midterm election. (That’s value changes minus inflation.)

There were six midterm years when such real home values were depreciating.

This list included the huge GOP loss of House seats in 1958 and 1974 — plus 1966 (47 Democratic seats lost), 1990 (eight GOP seats lost), 1982 (26 GOP seats lost) and 2010 (64 Democratic seats lost). Those years of real estate weakness averaged 41-seat losses for the party in the White House.

So what happens when U.S. home prices are on the upswing in a midterm year?

It’s good news for the party in the White House — a loss of only 17 seats in the House, on average.

How are we doing, so far? Real home values rose 11% in the past year.
