5 Things to Watch on Day 3 of the Democratic National Convention

We're halfway through, folks, with lots of political star power to come.

PHILADELPHIA, Penn.— -- The Democratic National Convention is halfway over, and after a hefty dose of drama in the first two days, it will feature some serious political star power in the final days.

Here are five storylines to watch out for today:

From the Present to the Future

The convention heard from two former presidents last night (Jimmy Carter by video and Bill Clinton in person), and tonight delegates will hear from soon-to-be former President Barack Obama and Vice President Joe Biden.

Both men have publicly lauded Clinton and supported her campaign, and Obama held a joint campaign appearance with Clinton in North Carolina earlier this month.

At that appearance, he said that no one has ever been “more qualified for this office than Hillary Clinton.” Meanwhile, Biden went on the offensive against Donald Trump and his running mate, Mike Pence, during an interview with ABC News on Tuesday at the DNC, saying, “These guys don’t know what they’re talking about” when it comes to ISIS.

Pitting One Billionaire Against Another

Former New York City mayor Michael Bloomberg very publicly considered running as a third-party candidate for president but decided against it, in March penning an opinion piece, headlined “The Risk I Will Not Take,” for his namesake news site.

A Democrat-turned-Republican-turned-independent, he will address the Democratic convention tonight and is expected to endorse Clinton.

In the opinion piece, he didn’t mention Clinton once but explained that he decided not to run because “my candidacy could lead to the election of Donald Trump or Sen. Ted Cruz. That is not a risk I can take in good conscience,” he said of the two Republicans who were in the midst of their party’s primary contest at that time.

Bloomberg detailed the issues he took with Trump’s campaign in the piece, and it seems likely that he will reiterate some of those points this evening.

Meeting Tim Kaine

While tonight may seem like a lineup of familiar political figures, one of the most anticipated speeches comes from Clinton’s vice presidential pick, Tim Kaine.

Though he has been a Virginia senator since 2013 and was the chairman of the Democratic National Committee for two years, the rest of his political career was largely focused on the state level.

Tonight will be an opportunity for him to introduce himself to the nation and help highlight some of the reasons Clinton went with him.

Racial Justice Likely Subject

The intersection of race and police has been a hot-button issue in light of the shooting deaths of several African-American men at the hands of police in recent weeks, as well as deadly attacks against police officers.

Those events will likely be addressed on the convention stage tonight because two of the best-known leaders in their communities are slated to speak.

Civil rights activist the Rev. Jesse Jackson is due to speak at the Wells Fargo Arena as well as former Philadelphia Police Commissioner Charles Ramsey, who was part of Obama’s 21st Century Policing Task Force.

Bernie in the Background

Bernie Sanders addressed the convention on the first night, and he was still very much on the minds of attendees on Tuesday, when he nixed the roll call nomination vote in an emotional moment.

As the week goes on, however, his planned presence will be lessened. There is no planned action on the floor, and he isn’t slated to make another address to the convention.

His supporters are still out in force inside and outside the arena, but the leader of that movement isn’t scheduled to play any further role at the party’s convention.
