From The New York Times:
KENNER, La. — Senator John McCain marked the unofficial beginning of the general election with a speech here Tuesday in which he sought to distance himself from President Bush and to argue that he has stronger credentials as an independent agent of change than his all-but-certain Democratic rival, Senator Barack Obama.
Mr. McCain has worked to unite the Republican Party by vowing to continue many of Mr. Bush’s policies, including continuing the war in Iraq, extending the Bush tax cuts and appointing conservative justices to the Supreme Court. But he used his speech here to highlight his independence from the president in areas including the early handling of the war, global warming and government spending.
“You will hear from my opponent’s campaign in every speech, every interview, every press release that I’m running for President Bush’s third term,” he said, trying to pre-empt one of the central Democratic strategies of tying Mr. McCain to the unpopular president. “You will hear every policy of the president described as the Bush-McCain policy. […]
[…] Why does Senator Obama believe it’s so important to repeat that idea over and over again? Because he knows it’s very difficult to get Americans to believe something they know is false. So he tries to drum it into your minds by constantly repeating it rather than debate honestly the very different directions he and I would take the country.”
“But the American people didn’t get to know me yesterday, as they are just getting to know Senator Obama,” Mr. McCain said, noting several instances in which he opposed the leaders of his own party.

CQ’s Presidential Support studies try to determine how often a legislator votes in line with the President’s position:
CQ tries to determine what the president personally, as distinct from other administration officials, does and does not want in the way of legislative action. This is done by analyzing his messages to Congress, news conference remarks and other public statements and documents.
So, these studies only track votes when the President has an explicit, stated opinion on a bill.
According to CQ, Senator John McCain has voted with President Bush 100% of the time in 2008 and 95% of the time in 2007:
