The 2008 U.S. election drew the highest turnout in decades

On November 4, 2008, the contest between Barack Obama and John McCain pulled Americans to the polls in numbers not seen for a generation. Roughly 131 million people reported casting a vote for president, up about five million from 2004 and the most ever recorded to that point.

Measured against the eligible voting population, the rate reached about 61.6 percent — the strongest showing in roughly four decades, a level the country had not matched since the late 1960s. Analysts pointed to an unpopular outgoing administration, economic anxiety, and an energizing campaign as drivers of the surge.

It was the highest turnout in the U.S. in decades.

The 2008 electorate was also the most racially and ethnically diverse in the nation’s history, with nearly one in four ballots cast by non-white voters. Turnout among young Black voters set a record, marking a notable shift in who shaped the result that day.
