Would a less bland VP pick have helped either candidate?

I will always think... that if Hillary had chosen Castro ... or even Booker... that she would have won.  I tweeted when she didn't chosen either of them (particularly Castro)- the it may end up being a sentinel mistake.  Either would have given her campaign the extra nudge to turn out enough minority & youth voters in the Larger cities in the few swing states to make the difference.
