The political story of the past two months is the Bush comeback, and the GOP’s comeback generally. Bush’s return to a 40 percent approval number in the Gallup poll is a significant fact, an indication that after a period of disaffection, Republican-aligned voters are (as the cliche would have it) “coming home.” You won’t read or hear much about this in the mainstream media, but assuming even only an extremelly mild continuation of the pattern — a few points upward — Democratic hopes for a huge wave of anti-GOP disaffection come November are in the process of being dashed.
