This article is about the award;
https://en.wikipedia.org/wiki/Time_Person_of_the_YearIt's supposely "profiles a person, a group, an idea, or an object that "for better or for worse... has done the most to influence the events of the year". This could make Kim Jong Un a real runner.
However a comment that suggests he's unlikely is;
"As a result of the public backlash it received from the United States for naming Khomeini as Man of the Year in 1979, Time has since shied away from using figures who are controversial in the United States for commercial reasons, fearing reductions in sales or advertising revenue."
Colin Kaepernick is a divisive figure in the States and could suffer accordingly.
So Macron is a shortish favourite and if the decision was made 6 months ago, I could see why. However the lustre has since worn off the Macron revolution somewhat so I can see him being readily opposed.
The #MeToo campaign at 2nd favourite looks more likely to me as it's current and it would be politically correct. However the problem with stuff like this is, the eventual winner might not even be listed. "American Women" won the award in 1975 and they could be honoured again as it would cover the #MeToo campaign too.
Taylor Swift could be a runner I guess but looking at previous winners, she probably doesn't have the requisite gravitas. Conor McGregor might be a better option in the 'novelty' runners.
Someone like Zuckerberg or Elon Musk could be runners as Bezos (Amazon) and Zuckerberg (Facebook) are previous winners. Zuckerberg has previously won (there have been a number of multiple winners) but I don't know if he has done anything this year to merit inclusion. Musk looks best to me from a tech viewpoint this year.
So in summary, I dunno
