One person took the Democratic Party convention by storm last night.

Someone who has never sought public office and whose greatest wish is to escape the goldfish bowl of Washington.

This was Michelle's night.

The First Lady's take-down of Donald Trump was masterly and she did it without mentioning his name.

Her pitch was brilliantly effective, arguing that America's president is, above all, a role model. Children, she said, need to be inspired by the life story and the values of the president.

Early on in the speech came the best line, her guiding principle for the Obama White House: "When they go low, we go high."

This was Michelle's plea for Americans not to back a candidate who makes veiled threats of violence, seeks to ban Muslims and deport millions of undocumented immigrants.

Certainly, her husband approved.

Hillary Clinton faced a tough opening day - the rift between her supporters and Bernie Sanders activists has been on very public display.

But Sanders himself came to her rescue. He gave Mrs Clinton a wholehearted endorsement.

With some of his activists in tears, distraught that Bernie will not be the nominee, he praised her policies on everything from healthcare to the environment.

A convention that was fraying at the edges - and which was threatening to hand the campaign momentum to Donald Trump - has been saved by the First Lady and the veteran Vermont Senator.

If she makes it back to the White House, this time as president, Hillary Clinton owes Michelle and Bernie, big time.
