Mary Trump has a strong political point of view — and it’s not shared by her uncle: She is a registered Democrat, according to the New York State Board of Elections. A Twitter account registered under her name includes tweets supportive of Hillary Clinton, whom Trump trounced in the 2016 election. It also contains endorsements of "Black Lives Matter” and an emoji of the LGBTQ rainbow flag.
She was not happy Donald Trump was elected: Invited to her uncle's election-night party in 2016, Mary Trump declined out of fear she "wouldn't be able to contain my euphoria when Clinton's victory was announced.” When Donald Trump won she tweeted: “This is one of the worst nights of my life. What is wrong with this country? I fear the American experiment has failed.’’ Mary also said: “Hillary Clinton is an extraordinary human being and public servant. That she lost to this is unspeakable.’’
