Democrats are likely to be pleased with the Moreno win in the GOP primary for Ohio’s Senate seat tonight. Because of his ideological extremity and endorsement from Trump, most Democratic strategists and political prognosticators believe him to be a weaker general-election candidate than his competitors would have been. Indeed, Democrats even took out ads in favor of Moreno, trying to boost him to exactly this outcome.
This is not a completely baseless idea. After the 2022 midterms, I found that GOP primary candidates who were endorsed by Trump went on to lag the predictions for general-election Democratic by a vote margin of about 5 percentage points. That large of an effect could tip a close race in Ohio, so the expected vote calculus likely favors Democrats here.
But the political calculus is another matter. Democrats have been criticized in the past for endorsing Trump’s chosen candidates as an electoral strategy on the grounds that it increases the likelihood of Washington passing Republican policies and pushing Trump’s agenda. Given that the Senate is likely to go Republican in the fall, having Trump-endorsed Moreno in the halls of Congress may provide a higher ROI for Trump than having a Senator Dolan or LaRose. By pushing these ads, Democrats are betting the return on votes will outweigh the potential downside. That bet does not come without risk.
