Celebrities muscling in on politics is nothing new, and certainly not Stateside, where the line between politics and entertainment has often been blurred.

JFK was as much of a celebrity as he was a politician, and Ronald Reagan and Trump, arguably the worlds biggest reality TV star, both became famous in front of the camera before they took their seat behind the desk in the Oval Office.

But given all the A-List celebrities that supported Hillary Clintons campaign in 2016, we all know how that turned out. So what went wrong?

I think the whole celebrity endorsement on political campaigns has slightly been undone, says PR expert Mark Borkowski.

Referencing Clintons 2006 campaign, he says: You couldnt move for Beyonces, Jay Zs, Bruce Springteens, and it had absolutely no impact. The glamour of a celebrity picking up on a political cause has actually devalued over the last ten to fifteen years. Call it the Bono factor if you like. I dont think there is the same trust.
