serving as the state's governor for two terms. Nelson, considered the most conservative Democrat in the Senate, was the lone Democrat in Nebraska's Congressional delegation. This election was one of the most expensive in Nebraska history. In 2005, Ben Nelson raised $3.9 million for his re-election campaign. Pete Ricketts contributed $14.35 million of his own money to his campaign; he raised an additional $485,000 in contributions. The race also attracted national attention and generated several high-level campaign appearances. President George W. Bush appeared at a rally for Ricketts on November 5, 2006, in Grand Island, while then-U.S. Senator Barack Obama appeared at a fundraiser for Nelson and other Nebraska Democrats on May 5, 2006 in Omaha. However, he won re-election by a wide margin. Nevada Incumbent Republican John Ensign won re-election to a second term over Democrat Jack Carter, Navy veteran and son of President Jimmy Carter. Popular Las Vegas mayor Oscar Goodman had said in January that he would probably run, but in late April, he decisively ruled that out. Goodman did not file by the May 12, 2006 deadline. Carter's advantages included his formidable speaking abilities and kinship with a former U.S. President. On the other hand, Ensign was also considered to be an effective speaker and as of the first quarter of 2006, held an approximately 5-1 advantage over Carter in cash-on-hand. Ensign won a majority of the votes in every county in the state, with his lowest percentage at 53%. New Jersey Incumbent Democrat Bob Menendez was elected for a full term. The seat was previously held by Democratic Governor of New Jersey Jon Corzine. After Corzine resigned and was sworn in Governor, Corzine appointed Congressman Menendez on January 18, 2006. Menendez was challenged by Republican Thomas Kean, Jr. and seven other candidates. Filing for the primary closed on April 10, 2006. The primary election was held June 6, 2006. Menendez became the first Hispanic to hold a U.S. Senate seat from New Jersey, and was the first Latino elected to statewide office in the state. Menendez won the Democratic primary, with 86% of the vote, against James D. Kelly, Jr. Republican John P. Ginty, associate director with Standard & Poor's represented the conservative wing of the New Jersey Republican party. Kean was a moderate, and the son of the former Governor of New Jersey Thomas Kean. Kean won the primary by a 3-1 margin. The
