Save your money.. I read a few of your comments, you don't understand a thing about US politics.
Tulsi got less votes than every other woman. how is that going to help. she's not even welcome in the DNC. she already announced she's not returning next year and the DNC blacklisted her, on top of that she has a $50 mill lawsuit against Killary.
Hmm, if I am not mistaken, Biden repeatedly said, that it will be a woman. Politicians are rarely to be trusted with their words, but the betting markets also have no male candidate listed among the favourites:
Source: https://www.betonline.ag/sportsbook/futures-and-props/politics-futuresThe exchanges have Sanders and Romney listed with more or less the same odds (around @100.00) as B. Obama. Cuomo is 230+ and you can bet on Biden for 830^^

Since you mentioned Gabbard. You can see she is @61.00 in the screenshot - at Betfair Exchange she is @410.00, so always shop for the best odds, makes a difference longterm

Gabbard is someone who can get additional votes for Biden. I mean votes outside the traditional Democratic vote block. And she may help Biden in swing states and with some of the demographic groups. On the other hand, Kamala Harris may not get any additional votes for Biden. She can help him only in deep-Blue states and deep-Red states.
@tyKiwanuka, I haven't decided whether I should make a bet in favor of Tulsi for veep. May be I'll, but with a very small amount. The only confirmed bet as of now is in favor of Biden for the 2020 POTUS elections.
