In many ways, the results in Iowa — and polls in this state — suggested that the Democratic and Republican contests were to a large extent two-way races: Clinton and Obama for Democrats and McCain and Romney for Republicans.
Still, on the Democratic side, former Senator John Edwards of North Carolina was moving to try at least to make a showing here after coming in second to Obama in Iowa. On the Republican side, former Arkansas Governor Mike Huckabee was trying to show his strength beyond Iowa, where he won the caucuses.
