These politicians have mastered the art of the power selfie (see: the former president with Bill Gates, Hillary mugging with Meryl Streep and the Jimmy Kimmel family groupie snap). Their tweeted zingers often go viral, from Hillary’s dig at FOX News during the Super Bowl to Bill’s sassy parody of the 2012 “Texts from Hillary” meme on April Fools’ Day 2014. And there’s no doubt their Twitter accounts will continue to be scrutinized as political junkies wait to see if the former Secretary of State will run for president in 2016. —Olivia B. Waxman
