( CNN) Donald Trump won the presidency in 2016 with the electoral college. But in three states( Michigan, Pennsylvania, and Wisconsin ), his margin over opponent Hillary Clinton was less than 50,000 votes each. In fact, just 77,744 total votes in those three states separated the two candidates. If Clinton had won all three, she would've been victorious over Trump. But she wasn't. Every vote mattered in the 2016 election.

It's impossible to say that the Russian influence campaign specifically changed the minds of African-American voters or turned them off to Clinton or that it didn't play into divisions that were already festering in the country and the party.

But it is absolutely true that the number of African-American voters who participated in the election declined sharply in 2016, according to the Current Population Survey. It was the largest decline in turnout among African-Americans since collecting began on the data in 1988. Just 59.4% of eligible African-Americans voted in 2016, down from 66.2% who reported voting in 2012. The deterioration is likely in part due to the absence of President Barack Obama, the nation's first black President, on the ballot. He helped drive historic turnout in the African-American community in both 2008 and 2012. But 2016 was the first time there had been a decline in Black turnout since 1996.
