PHOENIX John McCain's complex relationship with President Bush can be summed up with a simple saying: can't live with him, can't live without him.
The president's own popularity is bottom-of-the-barrel low. Even allies privately fret that he's an albatross for the Republican looking to succeed him.
But Bush also is beloved among GOP loyalists. He's a proven campaigner who can raise serious money. Those are huge assets as Arizona Sen. McCain works to rally the Republican base and fill his coffers while facing the Democrats' unrivaled enthusiasm and record-breaking fundraising.
The president and his would-be successor appeared together Tuesday for the first time in nearly three months at an event that epitomized both elements of their tricky alliance a fundraiser with GOP faithful at a private home, without the media to document it.
By the McCain campaign's own planning, the only time Bush and McCain were captured on camera was after the event too late for most evening newscasts on the airport tarmac in the shadow of Air Force One, just before the president departed.
All smiles, Bush and McCain shook hands and then waved at reporters but kept a safe distance and spurned efforts to get them to talk. Bush then boarded the plane as the senator and his wife, Cindy, watched from the ground. The goodbye lasted less than a minute.
McCain's fundraisers typically are closed to the press; the White House deferred to the campaign. Tuesday's fundraiser at the home of prominent Republican Jack Londen and his wife, Lynn, raised an estimated $3 million for the Republican National Committee.
Democratic opponent Barack Obama, an Illinois senator poised to become the Democratic nominee, got in a jab in advance.
"No cameras. No reporters. And we all know why. Senator McCain doesn't want to be seen, hat-in-hand, with the president whose failed policies he promises to continue for another four years," Obama chided while campaigning in Nevada. "But the question for the American people is: Do we want to continue George Bush's policies?"
For months now, Democrats have portrayed McCain as an extension of Bush. They have argued that McCain offers the same policies, despite his willingness to break with the Republican Party on a range of issues. And, they ran ads showing footage of Bush and McCain embracing each other in 2004, including one that said: "If all he offers is more of the same, is John McCain the right choice for America's future?"
The liberal group MoveOn.org also unveiled a commercial Tuesday that links images of Bush and McCain over the theme song of the "Patty Duke Show," a 1960s sitcom about identical teenage cousins who "laugh alike, they walk alike, at times they even talk alike."
Bush and McCain last appeared together publicly the day after the Arizona senator sewed up the nomination in early March.
The president welcomed the GOP's new standard-bearer to the White House at a brief Rose Garden news conference. It was a somewhat awkward scene. McCain fidgeted and said repeatedly that he'd welcome campaigning with Bush "in keeping with the president's heavy schedule." Bush, for his part, seemed eager to hand off the reins, saying the McCain would be making the hard decisions and "I'm going to be in Crawford with my feet up."
Mindful of the risks Bush brings, McCain has been aggressive about separating himself from the president. He has been laying out his own vision for the future with speeches on a slew of high-profile issues such as the U.S. posture in the world, climate change and the response to Hurricane Katrina.
During one such address Tuesday in Denver, McCain sought to contrast what he portrayed as a bipartisan vision on nuclear nonproliferation with that of Bush, who critics contend has engaged in partisan go-it-alone cowboy diplomacy that has strained U.S. relations across the globe.
In a way, even the White House is aiding in McCain's effort to chart his own course.
"President Bush isn't on the ticket," Dana Perino, the White House press secretary, said Tuesday in what has become a familiar refrain for characterizing Bush's campaigning on behalf of McCain. "At the end of the day, any candidate who's running for office has to stand on their own two feet. They have to chart a course for themselves. Every election is about change."
Still, a prideful White House has delicately tried to deal with McCain's not-so-subtle efforts to distance himself. When the president isn't by McCain's side, the White House offers lots of reasons: Bush is busy abroad, he's the commander in chief.
McCain has struggled to break from Bush on two key issues the Iraq war and the economy. Both men support continued military involvement in Iraq, and they both seemingly back the same free-market economic principles. And that has given Democrats plenty to talk about.
To be sure, Bush seems aware that he could be a drag on McCain. In March, the president said: "If my showing up and endorsing him helps him or if I'm against him and it helps him either way, I want him to win."
Earlier this month, Bush seemed by design or not to assume the traditional lame-duck presidential role in trying to assist the GOP nominee-in-waiting.
In a speech to Israel's Knesset, Bush spoke of the president of Iran and warned against appeasing terrorists, which some interpreted as a slap at Obama, who has said he would be willing to meet with heads of state in places like Iran. Obama used Bush's remark to lump the president and McCain together.
McCain aides insist they had no advance knowledge of the president's remarks, and the White House publicly denied the comments were directed at Obama. Still, the episode underscored the pitfalls and benefits as well as the evolution of the Bush-McCain association.
In 2000, the two squared off in a bruising battle for the GOP nomination. Bush won but the scars for McCain lingered for a while, and, to this day, GOP operatives can be divided into Bush and McCain loyalists. In 2004, McCain embraced Bush, figuratively and literally, and campaigned on his behalf even as he railed against the president's Iraq policy and called for more troops.
Some two years later, as McCain launched his own White House bid, he found himself on the same page with Bush on Iraq as the president adopted his push for a troop build up. The two also were in agreement on the hot-button issue of eventual citizenship for millions of illegal immigrants in the country.
The combination led some of McCain's core supporters to worry that he was carrying Bush's water, and endangering his own presidential prospects in return.
