Mrs Obama first used the slogan in her speech at the 2016 Democratic National Convention, which announced Hillary Clinton as the Democrat nomination for that year’s presidential election. Mrs Clinton would lose out to Donald Trump. Speaking to CBS’s Gayle King, Mrs Obama explained: “It has to be true – you know, look, that’s the one thing people ask me about, in this climate, how do you find it in yourself to go high.
“And here’s the thing, going high is a long-term strategy – because the truth is, going high is about thinking about trying to really get to the real answer, because a lot of time the low answer is our immediate instinct.
“It’s just, I’m mad, I want to punch you in the face, but it doesn’t solve anything.”
Despite Mrs Obama not running, several commentators have suggested Mrs Obama is the only person capable of beating Trump in the 2020 Presidential election.
Steve Lopez of the Los Angeles Times wrote: “I can think of only one person who would beat Trump, hands-down, no problem.
“It’s a long shot, sure, but the very idea of Michelle as a candidate would give Trump fits.”
The former First Lady had said in interviews she was not interested in running for office but Mr Lopez said: “I understand and respect that. But we can hold out hope, can’t we? No offence to Amtrak and Conan O’Brien, but unless and until Michele Obama tells it to a higher authority — like Ellen DeGeneres — the dream is alive.”
Trump is currently facing Bill Weld and Illinois Congressman Joe Walsh for the Republican nomination.
New York Senator Kirtsen Gillibrand pulled out of the running for the Democratic nomination.
Barack Obama’s Vice-President Joe Biden is second.
Vermont Senator Bernie Sanders is third.
Other notable candidates include New Jersey Senator Cory Booker, New York City mayor Bill de Blaiso, Hawaii congresswoman Tulsi Gabbard, California Senator Kamala Harris, author Marianne Williamson and entrepreneur Andrew Yang.
Under US law, Trump can only serve one more term as POTUS.
Trump sought the Reform Party nomination in 2000 but later pulled out.
He joined the Reform Party in 1999 after previously being a Republican.
