“The economy is just so damn strong right now and by all historic precedent the incumbent should run away with it,” said Donald Luskin, chief investment officer of TrendMacrolytics, a research firm whose model correctly predicted Trump’s 2016 win when most opinion polls did not. “I just don’t see how the blue wall could resist all that.”
Models maintained by economists and market strategists like Luskin tend to ignore election polls and personal characteristics of candidates. Instead, they begin with historical trends and then build in key economic data including growth rates, wages, unemployment, inflation and gas prices to predict voting behavior and election outcomes.
...Still, Luskin, Fair and other analysts who use economic data and voting history to make predictions also note that a sharp decline in growth and an increase in the unemployment rate by next fall could alter Trump’s fortunes.
“It would have to slow a lot to still be not pretty good,” Luskin said, adding that what really matters is the pace of change. Even if overall numbers remain fairly strong, a sharp move in the wrong direction could alter voting behavior.
Luskin’s current model — which looks at GDP growth, gas prices, inflation, disposable income, tax burden and payrolls — has Trump winning by a blowout margin of 294 electoral votes.
