In tight Democratic race, O’Malley’s Iowa support matters

DES MOINES, Iowa (AP) — In Iowa's leadoff presidential caucuses, longshot Democratic candidate Martin O'Malley could finally be a player.
That's probably not because of any hidden depths of support for the low-polling former Maryland governor. Rather, the quirks of the Iowa process mean that candidates must have a minimum level of support in each of the state's nearly 1,700 voting precincts. If O'Malley backers can't reach the threshold, they will have to select another candidate.
