Actually, the way I read the story, Washington "drug" Hamilton out to western Pennsylvania in the spirit of, "Now let's go out there together and clean up YOUR MESS, Alex."
Hamilton was being cute -- "don't tax you, don't tax me, we'll tax those poor b*stards out there on the other side of the divide who don't have good representation in Congress and spend the money on deserving bankers in New York."
And BTW, it was the only time in U.S. history that the President put on a uniform and went on campaign at the head of a column of troops.
