If Trump wins, I doubt that he would pick up Rand....and I strongly doubt Rand would accept...but I do agree with the 2nd part of your statement, rand coming in to right the ship that has been sinking under both parties.
I think the Liberty Movement needs to keep as much distance from Trump as humanly possible (even if we under the table support him so he beats out Bernie or Hillary)...that way we can rip on him all through his presidency, and at the election, we can show a clear, un-hypocritical contrast.
Trumps election will give us prime condition to take 2020, what say you?
Of course he would accept. You don't turn down the chance to be VP. It makes it so much easier to become president.
