(CNN) - The Arizona Democratic primary remains a tight contest between Sen. Hillary Clinton and Sen. Barack Obama, with evidence suggesting that Sen. Ted Kennedy's endorsement is helping Sen. Obama.
More than half of voters in Arizona's Democratic primary say Kennedy's endorsement of Obama was important – and those holding this view voted for Obama by a wide margin.
Exit polls also suggest the Kennedy endorsement might have been influential among the state's Latino voters, who supported Clinton but by a smaller margin than in other states.
As elsewhere, white men supported Obama over Clinton by a small margin; white women voted for Clinton over Obama by a much larger margin. Latino women likewise voted for Clinton over Obama by a large margin, while Latino men were more evenly divided in their vote.
