PHOENIX (AP) -- Arizona Republicans go to the polls Tuesday to pick their nominee to replace retiring Republican Sen. Jon Kyl.

Businessman Wil Cardon launched an expensive and unexpectedly feisty campaign against Rep. Jeff Flake for the seat. Although Cardon in the past month has backed off his aggressive television ads and taken a more positive tone, the campaign had been marked by accusations of hypocrisy, broken promises and flip-flopping positions on the emotional issue of immigration.

The winner will face Democrat Richard Carmona, a former surgeon general under President George W. Bush

Arizona hasn't elected a Democrat to the Senate since Dennis DeConcini won his third term in 1988, but Democrats are hoping the costly primary attacks will make it easier for Carmona to win the general election.

Arizona's largest county expects low voter turnout

Arizona's largest county is expecting a low voter turnout during the state's primary election.

Maricopa County recorder Helen Purcell said Tuesday that roughly 7 percent of registered voters are expected to cast ballots at polling locations. She said voter turnout is around 30 percent if early ballots are included.

Tuesday is primary election day in Arizona, with Republicans deciding their U.S. Senate nominee and voters in both major parties deciding contested races in U.S. House districts.

Polls are open from 6 a.m. to 7 p.m. Early ballots accounted for more than half of the voters cast in the 2010 primary.

Republicans have a four-way race for the nomination for the Senate seat being vacated by Republican incumbent Jon Kyl. He's retiring and not running for a fourth term.
