Unlike contentious earlier events from Iowa to Florida, this one featured little television advertising, no debates and a small investment of time by Romney, Gingrich, former Sen. Rick Santorum and Texas Rep. Ron Paul.
A total of 28 Republican National Convention delegates was at stake in caucuses held across a sprawling state that drew little attention in the nominating campaign, but figures to be a fierce battleground in the fall.
According to the AP count, Romney began the day with 87 of the 1,144 delegates needed to win the Republican nomination. Gingrich had 26, Santorum 14 and Paul 4.
