Five Things To Expect At Democratic Convention

As the Democratic National Convention in Philadelphia gets into full swing, Sky News takes a look at the issues and people set to dominate the agenda.

1. Pops at Trump

Hillary Clinton cannot give a speech these days without repeating the mantra that Donald Trump is "temperamentally unfit to be president".

We can expect the assault on The Donald and his suitability for the White House to be a major theme of the convention.

2. Celeb speakers

Donald Trump was certainly able to summon a lot of family members to attest to his character in Cleveland, but Republican big-hitters were notably absent.

Hillary Clinton will call on a current and former president in Barack Obama and Bill Clinton, a sitting vice president in Joe Biden, current First Lady Michelle Obama and former rival Bernie Sanders.

The convention will hear from mothers of black men killed by police officers, plus a sprinkling of celebrities including Lena Dunham and Chloe Grace Moretz.

What's more, the likes of Snoop Dogg and Lady Gaga are set to perform in support of Mrs Clinton. Of course, Mr Trump had Scott Baio of Happy Days fame.

3. The email server scandal

Will the scandal, which has dogged the Clinton campaign, be mentioned… or will it be the elephant in the room?

Although it has been put to bed by the FBI, it is continually mentioned by those who don't like Mrs Clinton.

It feeds the questions of honesty and trust which remain the biggest concern that many Americans have about the candidate.

Polls show Mrs Clinton is the second least popular presidential candidate in history. The most unpopular is Donald Trump.

4. Families

One of the fascinating features of this presidential race is that potential "First Daughters" Chelsea Clinton and Ivanka Trump are reportedly good friends.

They were introduced by their husbands several years ago, both familiar figures on the New York social scene, and have talked openly of their friendship.

It has been reported that they have tried to avoid too much discussion of their relationship as the campaign has heated up.

Chelsea Clinton's speech to the convention though will invite some comparison to Ivanka's in Cleveland, which was largely well received.

Whether prospective 'First Gentleman' Bill Clinton's speech will cause as much fuss as Melania Trump's did remains to be seen.

5. Protests

Hillary Clinton's choice of Tim Kaine as her running mate confirmed, to many people, that this will be the establishment ticket.

At the Republican convention, the insurgents were on the stage and the establishment was on the floor. It will be the reverse in Philadelphia.

Whether the discontented Democrats can make their voices heard - possibly forcing an official delegate count - will be as interesting to watch as the shenanigans in Cleveland.

Fans of Sanders are certainly prepared to express their displeasure.

It is also possible that, like Cleveland, the protests outside will be pretty tame compared to the unrest inside.

Thousands are expected at protest zones around the city of brotherly love but, with extreme heat warnings in place, keeping literally cool might be the biggest challenge.
