A behind-the-scenes look at March on the campaign trail with Hillary Clinton

The busiest month of the Democratic primary (so far), in photos

March was the busiest month of the 2016 campaign so far: Democrats held 28 contests in 31 days and awarded almost half of the delegates up for grabs in the Democratic primary.

Hillary Clinton and President Clinton spent the whirlwind month traveling the country — hitting 18 states and fighting for every single vote.

Here’s a look back at a few great moments along the way.

Hillary waves to supporters from the stage at the Apollo Theater in Harlem, where she joined her fellow New Yorkers for a rally to close out the month.

“It is a thrill to be ‘live at the Apollo,’” Hillary told the crowd. “It is wonderful to be back home in New York.”
