42 million Americans cast midterm ballots early

More than 42 million Americans have already voted in the midterm elections. Data from the University of Florida Election Lab shows current turnout is tracking with the 2018 cycle. Political scientists observe that enthusiasm appears stronger among Democratic voters and unaffiliated citizens right now.

The 2018 election set a benchmark for high participation in a midterms. That year saw the highest turnout since 1914. Michael McDonald, a political scientist at the University of Florida, notes that this year's numbers may surpass that record. He describes the current patterns as uneven across party lines.

Registered Democrats and voters without a party affiliation are showing high engagement. Registered Republicans are participating at lower rates in the early voting window. Democrats have accounted for 44% of early votes. Republicans have cast about 31% of early ballots.

McDonald points to rising participation among young voters and minority groups. He expects this to be the most diverse midterm electorate in U.S. history. He cites high engagement levels among African American, Hispanic, and Asian American voters compared to white voters.

The data carries limitations. States like Maine, Iowa, Kansas, and Nebraska do not rely heavily on early voting. These states may see only a third of total votes cast before Election Day. Their results will differ from states with large mail or in-person early voting systems.

Republicans are expected to close the gap on Election Day. Final results will not be announced until after polls close on Tuesday, November 3.
