I think he’s trying to be the first president to vacation in all 57 states before the end of his first term.
He's probably going to need another term if he wants to hit that benchmark, Lord forbid.
If memory serves, he has golfed in VA, MD, NV, CA, FL, HI, NC and certainly ME very soon. In just under 18 months, he's managed to golf in (at least) 8 states which is the equivalent of about new state every 2.25 months, if my math is near correct. At this pace, he needs about 94 months to get 'er done.
Let's hope this is one record he doesn't break.
