5 Things to Watch for Day 2 of DNC

Democrats brought the drama to Pennsylvania, and we’re only a day in.

Reeling From the Fallout

The Democratic National Convention did not get off to a smooth start on Monday.

After that, the first three hours were full of outbursts and boos from Sanders supporters.

Roll Call Could Get Raucous

The first hours of the convention were rowdy as the floor broke into jeers throughout several speakers’ addresses.

The very first mention of Clinton sparked a round of “Bernie!” chants, which continued for much of the early part of the program.

The state roll call vote on the nomination, scheduled for late this afternoon, is going to pose and even bigger opportunity for any disgruntled Sanders voters to show their displeasure.

Both Clinton and Sanders have had their names placed into nomination for president at the convention.

This is largely a technicality, since bound delegates will vote for their candidates even if a name isn't in nomination. But it's a symbolic gesture for his supporters, and per party rules, it means more Sanders time on the convention floor today.

Maternal Movement

One of the more emotional moments among tonight’s speeches will likely come when the Mothers of the Movement take the stage.

The circumstances of their children’s deaths may be different, but all the women have endorsed Clinton’s campaign.

Protests in Philadelphia

Hundreds of protesters took to the streets in Philadelphia on Monday, and the drama in the city and outside the convention center seems unlikely to let up.

The demonstrations have generally been bigger than the ones held last week during the Republican National Convention. As in Cleveland, there have not been significant reports of violence.

There were no arrests as of Monday night, but multiple people were detained, police told ABC.

Bill Clinton Takes the Stage

He arrived in Philadelphia on Monday and attended a reception for members of Congress.

Clinton has a history of making an impact at Democratic conventions. In his lauded speech at the 2012 gathering in Charlotte, North Carolina, he made a 48-minute, wonky case for President Barack Obama’s re-election.
