Question: Which Presidential election that had Barack Obama on the ballot had the highest turnout nationwide? Passage:The incumbent President of the United States, Barack Obama, a Democrat and former U.S. Senator from Illinois, was first elected to the presidency in 2008, running with U.S. Senator Joe Biden of Delaware. Defeating the Republican nominee, Senator John McCain of Arizona, with 52.9% of the popular vote and 68% of the electoral vote, Obama succeeded two-term Republican President George W. Bush, the former Governor of Texas. Obama and Biden were reelected in the 2012 presidential election, defeating former Massachusetts Governor Mitt Romney with 51.1% of the popular vote and 61.7% of electoral votes. Although Barack Obama's approval rating in the RealClearPolitics poll tracking average remained between 40 and 50 percent for most of his second term, it has experienced a surge in early 2016 and reached its highest point since 2012 during June of that year. Analyst Nate Cohn has noted that a strong approval rating for President Obama would equate to a strong performance for the Democratic candidate, and vice versa.
