"She did a great job of energizing our base. I'm very proud of her,” he said at a press conference in Phoenix, his first since losing to Barack Obama three weeks ago. “It's one of the great pleasures I've had to get to know her and her family, and I think she has a very bright future in a leadership position in the Republican Party.
"....I knew that she would be an energizing factor, because she energized me," he added. "Our base, and most Americans, viewed Governor Palin as a breath of fresh air."
Taking a look back at the presidential contest, he said his campaign was dealt a fatal blow when public focus shifted from foreign policy to the faltering economy. “The American people - and I respect that decision, I don’t in any way criticize it – [decided] that the economy was of vital importance. And it is,” he said.
He also told reporters: “We worked hard, and we inspired a lot of people, Sarah Palin and I. I think we look back with pride."
The Arizona senator said that he’s planning to run for re-election in two years, and that an official announcement would come “at an appropriate time.” He praised the president-elect for his cabinet picks so far, especially his reported selection of Arizona Gov. Janet Napolitano – long mentioned as a likely 2010 Senate rival - as Secretary of Homeland Security.
Multiple sources have told CNN that Napolitano is Obama’s top choice for that post.
"I have already talked with her, and look forward to moving her nomination as quickly as possible through the United States Senate," said McCain. He said he is also planning trips in the near future to Iraq and Afghanistan.
Even with his stiffest competition is reportedly taking a pass, McCain’s home state has been trending blue - he beat Barack Obama by just 9 points - and the four-term senator told reporters Tuesday he’s expecting a “tough race.”
