Who won the 2008 New Mexico Democratic caucus?

Almost a full week after the February 5 New Mexico Democratic caucus, 100 percent of the results have still not been reported. Most sources show Hillary Clinton to be slightly ahead but every source shows different results and the race is close enough that the final 1 percent could swing the race to Barack Obama.

In a caucus there are no physical ballots to be counted, so why is it taking so long to tabulate the results? Why are all the media sources reporting different numbers? Any why is there such poor media coverage of this state’s results in a race that is so close?
