Can Clinton bring the Obama coalition to the polls?

The electorate that put Barack Obama in the White House in 2008 and 2012 was different from the one that elected Bill Clinton in 1992 and 1996. Obama also expanded the Democratic vote beyond its 2000 and 2004 boundaries.

This time around, Hillary Clinton lacks the charisma, popularity and progressive credentials Obama has enjoyed.

So can she keep the gang together? Can she preserve the Obama coalition on Election Day?

Obama is the only Democrat to win a majority of the popular vote since Jimmy Carter, who scored 50.08 percent in 1976. Obama's 53 percent in 2008 and 51 percent in 2012 were the second and third-highest percentages for a Democrat going back to World War II.

Obama helped drive people to the polls at a record pace. The 58.2 percent turnout was the highest since the 26th Amendment extended the franchise to 18-20-year-olds.
