Even though he lost, Obama gets the same number of delegates as Hillary in NH

Despite the fact that Hillary won the New Hampshire Democratic primary, she and Barack Obama will receive the same number of delegates to the party's nominating convention:

Sen. Hillary Clinton picked up nine delegates after winning Tuesday's New Hampshire Democratic primary by almost 8,000 votes. Sen. Barack Obama, who finished in second place, also earned nine delegates. Wait a second—since Clinton won, how come she didn't get more delegates?

Rounding and remainders. Democratic presidential candidates gain delegates in each state as long as they capture at least 15 percent of the votes, and they're awarded delegates in proportion to the amount of votes they receive in each district and statewide. New Hampshire had 22 delegates up for grabs this week. Clinton, who received 39 percent of the vote, got 39 percent of the delegates. Obama, who won 37 percent of the vote, got 37 percent of the delegates. That rounds down to eight delegates each. John Edwards, who just made the cutoff with 17 percent of the vote, received three delegates. This leaves three extra delegates, who are then allocated to the three candidates in turn.

I'm sure that there are lots of good reasons that the parties don't do something crazy like use a simple popular vote to determine their nominees. I just can't think of any right now.
