Gabbard is fucking awful. She supports autocrats (Assad, Saudis, etc) and has ties to right-wing Hindu nationalist government in India. She actively campaigned against same-sex civil rights throughout the mid-2000s. Her family is part of a cult which, if we listen to those who have left it, has some rather disturbing practices. Yeah, she has done things which appear to be good like support Sanders in his run, criticise the NSA or Americas rampant interventionism but it's important to look at the motive behind these actions.
I'd really recommend reading some pieces on her before cheering her along. The New Yorker did a profile on her in 2017 and Paste Magazine did one in 2016.

“Gandalf put his hand on Pippin's head. "There never was much hope," he answered. "Just a fool's hope, as I have been told.”
