Washington ? Enthusiasm among blacks and Democrats for Barack Obama’s candidacy pushed voter turnout in this year’s elections to the highest level in 40 years.

Final figures from nearly every state and the District of Columbia showed that more than 131 million people voted, the most ever for a presidential election. A little more than 122 million voted in 2004.

This year’s total is 61.6 percent of the nation’s eligible voters, the highest turnout rate since 1968, when Republican Richard M. Nixon defeated Democrat Hubert Humphrey, said Michael McDonald, a political science professor at George Mason University.

States finished certifying their election results this weekend, including California on Saturday. The Electoral College was scheduled to elect Obama president today, with electors meeting in each state to vote in a largely ceremonial procedure.

Turnout increased for the third straight presidential election, encouraging news for those who have warned about voter apathy. Four years ago, 60.1 percent of those eligible voted.

“We seem to have restored the levels of civic engagement that we had in the 1950s and 1960s,” McDonald said. “But we didn’t break those levels.”

McDonald calculated turnout rates based on the number of eligible voters among adult U.S. citizens. Experts calculate turnout rates in different ways based on whom they consider eligible voters, a process that excludes noncitizens and, in most states, convicted felons.

Regardless of the method, turnout fell short of many predictions, in part because voters in some Republican areas of the country were not as enthusiastic this year with Sen. John McCain as the party’s nominee as they were four years ago when President George W. Bush won a second term.
