If you read about today's Washington Post/ABC News poll online, you probably missed the "Act II, Scene I" sidebar graphic from the Post's print edition that is also available online. The gist if the graphic is that while the McCain-Obama vote looks now looks identical to Bush vs. Kerry preferences four years ago, the larger political terrain as defined by the Bush job rating, the perceived direction of the nation and views about the Iraq War are very different. . .
. . .Regardless of whether the current national horse-race is exactly the same as at this point in 2004, or a few points better for the Democrats, the larger point of the Post graphic still holds: We have seen far bigger changes in the percentage of Americans that disapprove of George Bush's performance as president (+17 percentage points since June 2004 in the ABC/Post poll), that say things in the country "have gotten pretty seriously off on the wrong track" (+27) and that conclude the war in Iraq was "not worth fighting for" (+11).
I really think the change in the perspective of the electorate on Bush and Iraq is a key difference between 2004 and 2008. To me, the difference in voters' outlook on the country is at least as important , arguably more important, than the candidates this time around.
