This is not as far fetched as some of you people make it sound like. Not the most likely ticket, no, but far from unthinkable. If Biden wants to use his VP pick to reach out to voters that he doesn't immediately appeal to, Yang is not such an awful choice and he certainly seems like the kind of person that would be easier to manage than someone like Sanders or Warren (not that they would accept being Biden's VP anyway). Also, I don't think it is a given that Biden's VP pick has to be a woman.

But it would drastically reduce my opinion of Yang, and i would see him as a sell-out, and now have increasing reservations over his commitment to socialist issues. I mean he's a businessman. Even just this rumor made me doubt him.
