I have seen him called assassination insurance for Trump.Tactically, Trump should name a minority, a female, or a governor that can bring in a valuable state.
That narrows it to Scott, Carson, Haley (lol- no chance), or Youngkin.
Having said that... does he even need a tactical pick? He might simply be far enough ahead to not worry about "tactical".
I'd LOVE Vivek... but outside of being "right" on the issues (which is not of much value), what does he bring?
