okay, answer me this: who is Tulsi's base in the Democratic Primary? I know the standard response to this is that she'll inherit all of Bernie's supporters because she endorsed him in 2016, but I don't see working class whites in places like McDowell County, WV or Ingham County, MI voting for a 39 year old Hindu Woman, and I certainly don't see College Kids or Affluent White Liberals voting for someone who's so favorable towards Putin, Assad, and Modi. Cornering the "anti-war vote" won't do it either: otherwise, Howard Dean would have been the nominee in 2004, and while this certainly helped Obama in 2008, it was just one factor in his appeal among many.
Barack Obama kind of invalidates the first part of your argument. Who cares if she's a Hindu woman?
Also most Americans don't even know who Modi is, and I don't see how she's favorable towards Putin and Assad. She's just more skeptical and less hostile in general when it comes to dealing with them. It's just the war hawks in this party who want to paint her as an ally of Putin and Assad.
Her base would be a combination of women, minorities, anti-war voters, and Bernie supporters.
