If Trump walks into the convention he has EVERY right to pick his OWN VP!!!!!
They always have, but I'm not sure if there has been a perfunctory nomination and vote on the nominee's VP pick in the past.
And the VP does give an acceptance speech. Recall Sarah's in 2008.
I'm wondering if the convention is required to nominate and vote on the VP selection, and if what has most always been perfunctory could be turned into another opportunity to undermine Trump.
That's a procedural question that has a yes or no answer.
