WASHINGTON -- A drop in voter turnout in Tuesday's election didn't keep President Barack Obama from winning a second term.
Preliminary figures suggest fewer people voted this year than four years ago, when voters shattered turnout records as they elected Obama to his first term.
In most states, the numbers were even lower than in 2004, said Curtis Gans, director of American University's Center for the Study of the American Electorate. Every state but Iowa is showing a smaller turnout than in 2008, Gans said. Still, the full picture may not be known for weeks because much of the counting takes place after Election Day. "This was a major plunge in turnout nationally," said Gans, who estimated about 126 million Americans voted, for an overall turnout rate of about 57.5 percent.
In Arizona, almost 19 percent fewer people cast ballots than in 2008. In Maryland, where voters approved a ballot measure allowing gay marriage, turnout in the presidential race was running more than 7 percentage points behind 2008. Alaska saw a drop-off of nearly 25 percent over four years ago, when former Alaska Gov. Sarah Palin was the Republican vice-presidential nominee.
With 99 percent of precincts reporting, The Associated Press' figures showed about 119.5 million people had voted in the White House race, but that number will increase as more votes are counted. In 2008, 131 million people cast ballots for president, according to the Federal Election Commission.
Experts calculate turnout in different ways based on who they consider eligible voters. A separate, preliminary estimate from George Mason University's Michael McDonald put the 2012 turnout rate at 60 percent of eligible voters, a drop-off of more than 2 percentage points from 2008. McDonald said the 2012 figure would likely be revised as absentee votes were counted.
Turnout in the nine or so most competitive states appeared to be, on average, a few points higher than in other states that the presidential candidates largely ignored. In Wisconsin, about 7 in 10 people of voting age cast ballots.
Large drops, according to the American University analysis, came in Eastern Seaboard states still reeling from the devastation from superstorm Sandy.
