CBS News: Bush's Top Ten Flip-Flops. My favorite:
During the 2000 campaign, George W. Bush argued against nation building and foreign military entanglements. In the second presidential debate, he said: “I'm not so sure the role of the United States is to go around the world and say, 'This is the way it's got to be.'”
The United States is currently involved in nation building in Iraq on a scale unseen since the years immediately following World War II.
During the 2000 election, Mr. Bush called for U.S. troops to be withdrawn from the NATO peacekeeping mission in the Balkans. His administration now cites such missions as an example of how America must “stay the course.”
[I think this one is actually a double-flip-flop since we're now abandoning nation-building in Iraq.]

CBS News: Kerry's Top Ten Flip-Flops. Most pandering and damning,
In October 2003, Kerry said Israel’s unilateral construction of a security fence was “a barrier to peace.”
“I know how disheartened Palestinians are by the decision to build the barrier off the Green Line,” he told the Arab American Institute National Leadership Conference. “We don't need another barrier to peace. Provocative and counterproductive measures only harm Israelis.”
But less than a year later, in February 2004, he reversed himself, calling the fence “a legitimate act of self-defense,” and saying “President Bush is rightly discussing with Israel the exact route of the fence to minimize the hardship it causes innocent Palestinians.”
The CBS writer’s account of the Bush reversal of steel tariffs is not quite accurate. Kuhn writes: “the Bush campaign decided it could afford to upset the steel industry rather than further estrange old alliances”. Such sentimentality is not the style of this administration. The European Union has real, centralised power over trade matters and used it, lawfully and credibly, to threaten very damaging and politically targeted retaliatory tariffs. Washington blinked first. The other story is spin.
It isn’t necessarily a flip-flop to say on the one hand that a security fence is necessary, not inherently immoral/illegal, etc, and to say on the other hand that for such a security fence to diverge from the Green Line and cut into the West Bank is wrong.
