Here are the unofficial election results from the Tuesday, Nov. 4, races as reported by the Nassau County Board of Elections: Barack Obama has become the 44th president of the United States. He made history Nov. 4 by becoming the nation's first African American commander in chief, besting Republican challenger John McCain. Nassau County residents voted as follows: 316,523 (Obama-Joe Biden) to 272,765 (McCain-Sarah Palin). Incumbent Republican Thomas Alfano also fought hard for his seat, besting Democratic opponent Alan Smilowitz 29,580 to 18,032 in the 21st Assembly District race. Assemblyman Alfano, of North Valley Stream, has served the Assembly since 1996. The 21st Assembly District includes, Elmont, Franklin Square, West Hempstead, North Valley Stream and Floral Park. According to Alfano's office, voter breakdown per town is as follows: Alfano captured 63 percent of the vote in the 21st Assembly District. In Elmont, Alfano won 7,289 to 6,969; in Floral Park, he won 5,129 to 1,803; in Franklin Square, he posted 7,806 votes to Smilowitz's 3,195. In his hometown of North Valley Stream, Alfano received 2,134 votes to 1,987. Finally, in West Hempstead, Alfano posted 2,678 votes to 1,647. "This truly was democracy in action," he said the day after his win. "It's historic and I'm very proud of everyone who was out there casting their ballot. I want to personally thank everyone for their tremendous vote of confidence. This was a huge victory."

In a highly publicized race for the 4th Congressional District seat, incumbent Democrat Carolyn McCarthy proved victorious, besting Republican challenger and Mineola mayor Jack Martins 153,320 to 87,239. "I am honored to have been re-elected by the people of the 4th Congressional District with such resounding support," she told Anton Newspapers. "I am looking forward to returning to Congress and continuing my work to bring the needs and concerns of Long Islanders to Washington."

McCarthy, who resides in Mineola, was first elected to office in 1996, to enact stricter gun laws after her husband, Dennis, was shot and killed and her son, Kevin, injured in what became known as the Long Island Rail Road Massacre. She was the first woman elected to Congress from Long Island. During her campaign, McCarthy was criticized by some who accused her of never taking a stand on the LIRR/MTA's controversial project to add an additional track to the Main Line.

Incumbent Democrat Craig Johnson fought hard for his 7th Senatorial District seat, besting Republican opponent Barbara Donno 63,470 to 49,050. In 2007, Johnson won a special election, making him the first Democratic senator of the 7th District in a century. The seat had been vacated by Republican Senator Michael Balboni, who resigned to become then-Governor Eliot Spitzer's choice to head New York's homeland security. Prior to being elected to the State Senate, Johnson served four terms in the Nassau County Legislature. Residents voted yes to NYS Proposition 1, which will enable the Nassau County assessor's position to be appointed rather than elected. The referendum, which was approved by a vote of 89,963 to 78,438, enables the county executive to appoint the chair of the board of assessors for a three-year term - subject to the county legislature's confirmation - rather than have residents vote the chair to a six-year term. Democratic Legislator Wayne Wink made the proposal in order to "take politics out of the assessor's office." The change would not take effect until January 2009, a year before current assessor Harvey Levinson's term expires; he supports the proposal.
