There’s a first time for everything, and for Dwyane “The Rock” Johnson, that would be a presidential endorsement. You’d think it would take a really exceptional candidate to drag the self-proclaimed independent out of his apolitical status and into the 2020 fray. But you’d be wrong because The Rock is putting his pristine reputation on the line for none other than Joe Biden and Kamala Harris, with an Instagram post that racked up 3 million views in just a matter of hours.

Do these kinds of celebrity endorsements end up making any significant difference for the politician receiving them?
