Just hours after the last voters walked away from Iowa's caucuses, the center of the reshaped 2016 presidential race shifted to New Hampshire, where candidates were already addressing voters before dawn Tuesday.

The first-in-the-nation primary, held on next Tuesday this year, often contradicts the preferences of Iowans, rewarding moderate politicians who invest time in the state. For many candidates, the sprint will include three or four events daily in school gymnasiums, town halls or Veterans of Foreign Wars posts, each of which might feature an hour of taking questions from a potentially hostile public.

"The best eight days in American politics," said Tom Rath, the state's former attorney general and an adviser to Ohio Gov. John Kasich, whose presidential hopes are so tightly pinned to the state that he didn't even leave for the Iowa caucuses.
