Gabbard would seriously be one of the worst candidates the Democrats have ever had. She has no commitment to progressive principles, is influenced by Breitbart benefactors, and has little to no experience governing. Aside from all of this, she's associated with right wing groups in various foreign countries.
I wouldn't be surprised if she lost 40 states to Trump. This Democrat Party is a mess.
Tulsi Gabbard is actually the type of Democrat that appeals to real-life people. The Atlas demographic is irrelevant.
