Vance is 40 years old. He has a lot of runway in front of him. Early indications are that he's hiding at least some of his power level, but that could just as easily be a deliberate mirage. We won't really know for sure until/unless he becomes president. The Indian wife and kids are an obvious red flag, but he seems to be on the right side of the H-1B divide. I guess we'll all find out together.

My money is still on Barron eventually becoming the chosen one, but sometimes these things happen out of order or unexpectedly.
