No-one Perfect, PERIOD!
JD is good VP pick for one reason 
(yes, lots  GOOD (again, not Perfect) choices, all have good/bad, pros/cons, and the like regarding Election strategy, but IMO)
JD's background. His having grown up poor and his Family Life that shows he's AN AVERAGE PERSON not a pampered insider; the part I am referring to is way HILLBILLY ELEGY book and the "Hillbilly" language endearingly rather than how Left always tries use as pejorative (Flyover fools) 
And it is NOT just about reaching POOR WHITE FOLKS but all not in the Leftists favored #IdentityPolitics dividing - but proud, folks think for selves, work for what have, care about Family and America as 'Land of Opportunity' and FREE to WORK to achieve for self/Family/Nation betterment, etc... And THAT IS NOT SKIN-TONE SPECIFIC  (despite the usual "Hillbilly" connotation; and about damn time WE start using Language better on our Side)! Left twists language, WE MUST RECLAIM IT!
You, me, we, may not like Identity Politics, but Abraham Lincoln DID NOT just get to say "Gettysburg Schmettysburg, let 'em have it" (and then the South could have marched into virtually anywhere else into North they damn well pleased). Your opponent/Enemy sometimes dictates BATTLE GROUNDS WHICH YOU MUST FIGHT and make no mistake this HELPS in the Identity Politics battle without the obvious clear PANDERING (would be declared by #MSM #ENEMEdia Leftists, while ignoring all the actual pandering of/by Left/Fascicrats) of picking a Female or a "Person Of Color" (but I would have been VERY HAPPY with a Kristi Noem (for right reasons, again, all have pros/cons, her being Female just BONUS) or a Tim Scott (again, plenty of GOOD REASONS WHY, and his skin-tone BONUS in the Identity Politics game THE LEFT we all know will try play).
