With Obama riding high in the polls, comparisons between John McCain and Bob Dole are gaining ever more currency. Former Hillary campaign flack Howard Wolfson has gone as far as declaring it’s over:

Perpetually fretting Democrats will not want to accept it. The campaigns themselves can’t afford to believe it. Many journalists know it but can’t say it. And there will certainly be some twists and turns along the way. But take it to a well capitalized bank: Bill Ayers isn’t going to save John McCain. The race is over.

Last Saturday, Wolfson went as far as penning a “premortem for the McCain campaign“, and was promptly criticized for it by ABC News’ Jake Tapper. On his blog, Tapper warned Obama backers to “Check Yourself Before You Wreck Yourself“:

Buoyed by encouraging poll numbers [..] lots of Obama backers out there seem to think this thing is over. [But that’s] not what lots of smart folks in the Obama campaign think. They believe Obama’s poll numbers are artificially high, McCain’s are artificially low, this race will come down to two or three points, and anything could happen.

As Anne Kornblut and Jon Cohen in the Washington Post today remind us, “recent history suggests that mid-October leads are vulnerable […]”.

Is Tapper right? Should we check ourselves before rejoicing too early, only to find ourselves flat-footed when the numbers unavoidably narrow again? That’s always a piece of advice that’s close to my heart, but it bears mentioning that Tapper cherry-picks his data to make the point.
