Tulsi will be the VP candidate for the dems, prezactly because of her military service. Also, she is a raging extremist.
Possible, I guess, but unlikely.
If somebody considered far to the left is nominated she might balance the ticket.
But Hawaii is solid Democrat and Samoan Hindus aren't a very large voting bloc and if Democrats really want somebody closer to the center as VP, they'll look for somebody from the mainland.
