The next big competition is in New York and Trump leads in the Empire State polls.
But the greatest benefit of competing in his own backyard is that after nine weeks of non-stop rallying, Trump might actually get a break.
Imagine kissing all those babies and shaking all of those hands.
Imagine feigning interest in all of those individual lives. Imagine needing to be reminded of whatever dire little county you were visiting, in whatever godforsaken corn-belt state.
Imagine Googling yourself 50 times a day and being hounded by 100 news cameras. Imagine all the fake smiles.
Running for President is an exercise in extraordinary endurance.
Fly. Speak. Fly. Speak. Fly. Speak. Repeat.
Forget Richie McCaw and GODZone.
Criss-crossing the US while running for the White House is enough to shave years off a normal person's life.
Most of us would go troppo. Most of us would lose the plot.
And - sure - maybe Trump is finally faltering.
But then maybe again, all he really needs is a good 12 hours' sleep.
