Which One of These is Sasha Obama's Secret Twitter?

In his first joint campaign appearance with Hillary Clinton, prominent narc Barack Obama let slip that his daughter, Sasha Obama, tweets . Meaning that Sasha’s covert days on Twitter are just about over.
Obama actually revealed the secret as an aside in a burn on Trump, saying, “Everybody can tweet, but nobody knows what it takes to do the job until you’ve sat behind the desk. I mean, Sasha tweets.”
It’s only a matter of time before the internet’s many amateur detectives uncover the youngest First Daughter’s Twitter hideaway. We’ve managed to narrow down the field using some clever context clues. One of the below tweeters is without question Sasha Obama—can you figure out which?
