With that in mind, who is your suggestion, and why?
Well, the VP is officially the President of the Senate and, unofficially, insurance against assassination (eg: Biden). Given that if Trump is in any way successful with Make America Great Again there's going to be a lot of people displaced from power and wealth the likelihood of assassination attempts are really pretty high, so we need someone who is jut so much more unacceptable to these corrupt globalists than Trump.
To this end, I think Mr Trump would do well to have a VP that was an "ultra-constitutionalist" if you will — someone who, like me, would in the Presidency simply dissolve all federal agencies that aren't directly chartered/authorized by the Constitution, which would come out to something like: Dept. of Transportation (roads/making commerce regular), Post Office, Army, Navy, IRS (sadly), Coast Guard and INS (customs and immigration), and Secret Service (counterfeiting investigations, no protection services). (I've actually been called an anarchist because of my view there.)
Another way to go would be Theodore Beale, the author of SJWs Always Lie and Cuckservative — his anti-globalist nationalistic stance is very strong, strong enough that he explicitly and forcefully rejects Free Trade. (I think he'd also have the ability to drive the PC media nuts, much like Trump does.)
If he wasn't so old, Ron Paul would make an excellent choice, too — his anti Federal Reserve stance (Audit!) alone would probably be enough to frighten the power-elite. (The fraud that is the Federal Reserve is amazing in its scope and breadth, any but the most cursory/superficial investigation will start that edifice crumbling.)
