I guess she takes more after her granddad George, who's also said to be voting for Hillary.
Barbara Pierce Bush appeared alongside Hillary Clinton's longtime aide Huma Abedin in a photo posted Saturday evening by a prominent fashion-industry insider, branded with a #werewithher hashtag.
Lauren Santo Domingo, contributing editor at Vogue, and actress Dakota Fanning, who has donated to Clinton in the past, were also pictured in a selfie taken with Derek Blasberg, Vanity Fair's "Man on the Street" and a well-known New York socialite with an Instagram feed that has more than half a million followers.
Blasberg is also a self-declared Democrat.
Bush's grandfather, George H.W. Bush, is voting for the Democratic nominee, Kathleen Hartington Kennedy Townsend revealed last month in a photo on Facebook.
Blasberg later deleted the tweet and reposted it, without the #werewithher hashtag.
