In the good old days, a consideration of how many electoral votes a VP could bring was a big part of the selection.
Love him or not, I doubt North Dakota Governor Doug Burgum would bring enough to put the puck in the net.
Trump doesn’t need anyone to help him get votes. He needs someone who’ll have his back. Love him or hate him, people have strong opinions about Trump. Few are going to change their feelings about him based on his VP candidate unless it’s someone so extreme that he ends up alienating his base (e.g. RFK Jr., Gabbard).
