As the designated political heir of a deeply unpopular president  according to Gallup, President Bush has the highest disapproval rating recorded in 70 years of polling  John McCain should have little hope of winning in November. In fact, however, current polls show him roughly tied with either Democrat.

In part this may reflect the Democrats’ problems. For the most part, however, it probably reflects the perception, eagerly propagated by Mr. McCain’s many admirers in the news media, that he’s very different from Mr. Bush  a responsible guy, a straight talker.

But is this perception at all true? During the 2000 campaign people said much the same thing about Mr. Bush; those of us who looked hard at his policy proposals, especially on taxes, saw the shape of things to come.

And a look at what Mr. McCain says about taxes shows the same combination of irresponsibility and double-talk that, back in 2000, foreshadowed the character of the Bush administration.
