Puzzle

By Eugene Volokh

I thought I?d repeat a puzzle that I first posted five years ago.

Put these in order by moving the fewest names:

Washington, Wilson, Johnson, Johnson, McKinley, Davis, Jackson, Taft, Kennedy

Moving a name to between two other names, before the first name, or after the last name all count as one move. Thus, exchanging #2 and #7 requires two moves (since you?d have to move #2 and then move #7).

Note that ?order? need not necessarily mean chronological order.
