Republican Gov. Jeb Bush, the president's younger brother, survived a spirited challenge from Democratic Tampa lawyer Bill McBride, 56 percent to 43 percent, to win a second term in Florida.
"Fifteen minutes ago Bill McBride called me and graciously conceded the election. I told him he ran a hard race and I look forward to working with him to build the state of Florida," Bush told supporters in Miami. He also thanked his family for helping him win.
"I want to thank the president for coming down and lending a hand to his little brother," he said.
President George W. Bush, former president George H.W. Bush, former first lady Barbara Bush, first lady Laura Bush and Vice President Dick Cheney all campaigned for Jeb Bush in a political test of the popularity of the Bush dynasty.
A Bush loss in Florida would have been a personal embarrassment for the president and a major coup for the Democrats. Former President Bill Clinton and former Vice President Al Gore raised funds and stumped for McBride, who defeated former attorney general Janet Reno in the Sept. 10 primary.
President Bush called his brother from the White House to congratulate him.
"The president was particularly delighted about his brother's win. He is very proud of Gov. Jeb Bush and his win by a very large margin in Florida. It is important to note that the chairman of the Democratic National Committee said the Florida's governor's race was the DNC's No. 1 priority, and they did not achieve their No. 1 top priority. It was a poignant moment watching the president watch his brother give his acceptance speech," said White House Press Secretary Ari Fleischer.

In Texas, Republican Gov. Rick Perry declared victory over Laredo millionaire Tony Sanchez, 58 percent to 40 percent, in his bid for a full, 4-year term, but the state's first Hispanic candidate for governor refused to concede late Tuesday.
"We must seek common ground to achieve the common good," Perry told a cheering crowd. "Yes, we are Republicans, Democrats, independents, and yes we are a diverse tapestry of different people from different backgrounds but first and foremost we are Texans."
Just a few minutes after Perry left the podium to a cheering crowd at the Republican victory party in Austin, Sanchez strolled in front of his supporters at another hotel as they shouted, "Tony, Tony, Tony."
Sanchez said Perry's speech reminded him of 1948, a reference to the famous presidential election in which Democrat Harry S. Truman was elected president after Republican Thomas E. Dewey had declared victory.
"I'm still going to give him hell until the last vote is counted," a defiant Sanchez said.
Sanchez, a banker and oilman, spent more than $60 million of his own money in a long and bitter campaign to defeat Perry, a veteran of nearly 18 years in state office who succeeded George W. Bush when he was elected president. Perry was lieutenant governor and automatically assumed the governor's post.
Sanchez refused to concede because of voting problems in Tarrant and Bexar counties, two of the state's most populous urban areas. Perry's had a 58 percent-to-40 percent lead over Sanchez with 89 percent of the vote counted.
Richardson, a 54-year-old former U.N. ambassador and energy secretary, ran on his government experience against Sanchez, a 39-year-old state legislator and roofing contractor who claimed a rags-to-riches story. Richardson, the state's first Hispanic governor in 20 years, will succeed Republican Gary Johnson who had to step down due to term limits.
