What happens to delegates when a candidate withdraws or suspends their campaign?
In the United States Presidential Primaries, what happens to a candidates delegates if they later withdraw from the race? For example, in the [2016 Republican Presidential Primary for the State of New Hampshire](http://www.thegreenpapers.com/P16/NH-R), Donald Trump would win 11 Delegates, John Kasich would win 3, Ted Cruz would win 2, Jeb Bush would win 2 and Marco Rubio would win 2. What happens to these delegates if/when one of these candidates withdraws from the Presidential race? Are they awarded to the withdrawn candidate anyway? Divided up between the remaining candidates in some proportion?
