Bush has been accusing Kerry of flip-flopping, primarily based upon gross distortions of Kerry’s voting record in Congress. When these accusations are looked at closely, they do not hold up at all–but Bush is on record as one of the biggest flip-floppers of all time. One prominent example is his position on the Iraq war and WMD:

First Bush claimed that he did not need Congressional approval to go to war with Iraq. Then he flip-flopped and decided he did need their approval. Then Bush decided he would not go to the U.N. for a resolution on the matter, and then he flip-flopped and decided he would go. But soon after, he flopped on his flip-flop and decided that he didn’t need the U.N. after all.

Then there was his ever-flipping position on WMD. At first he was consistent: in November 2002, before he invaded, he said that Iraq had weapons of mass destruction, and that’s why we had to invade. Then after the invasion, in May 2003, he said that he had actually found weapons of mass destruction. But then he had to flip-flop and admit we hadn’t found actual weapons yet, really.

But then he switch-flopped in June and said that Hussein had a weapons of mass destruction program, and that was why we went into Iraq. But then he had to admit that there was no evidence that Hussein had such a program since a decade ago. And by the State of the Union speech last January, he flip-flopped again with a backwards twist and a triple gainer, this time claiming we had found “weapons of mass destruction-related program activities.” Finally, when he had no choice but to face the facts, he admitted that there are no weapons of mass destruction in Iraq, and upon doing so, did a huge, monolithic, record-breaking warp-speed flip-flop and claimed that the reason we went into Iraq was for humanitarian reasons.

An then let’s not forget one of his most gigantic flip-flops, so sudden and absolute that Bush must have gotten whiplash:

December 13, 2001: We will get Osama bin Laden, no matter how long it takes, “dead or alive — either way. It doesn’t matter to me.”

March 13, 2002 (exactly three months later): “I don’t know where [Osama bin Laden] is. I have no idea and I really don’t care. It’s not that important.” And on the same day: “I — I’ll repeat what I said. I truly am not that concerned about him.”

It’s hard to get more flip-floppy than that. But Bush has a long record of flip flops. The major ones are covered in many places, like here, here, here, and a long list here.
