  I love how the major party standard bearers re-invent themselves once the primary season gives way to convention season. For example, compare the rhetoric of GWB at Bob Jones in SC to his rhetoric at the convention with the veritable rainbow coalition of diverse speakers and words of compassion.
Also consider, for example, Kerry's "evolution" (from the WSJ): Redefining Benedict Alert bloggers have picked up on some subtle airbrushing of the John Kerry website, belatedly catching up with the candidate's transformation from Howard Dean manqué to confidence-inspiring moderate. The father and daughter team of John and Jessie Rosenberg at www.discriminations.us report that all website references to Benedict Arnold CEOs have been carefully revised. The phrase now applies only to executives who move their companies offshore as a corporate tax dodge. Previously, it had been used to slap around any executive who sourced production overseas, benefiting enemy workers at the expense of Americans. So what else is new? Around convention time is when every Democratic nominee disowns the ranting, populist self of the primaries and recruits a gaggle of corporate bigwigs (ideally former "lifelong Republicans") to testify to his fiscal moderation and sobriety.
Sure enough, "CEOs for Kerry" was splashily unveiled last month, and even earlier he had less than artfully disowned his Benedict Arnold soundbite as the product of "overzealous speechwriters" -- notwithstanding a long trail of quotes suggesting that Mr. Kerry used the phrase in ad lib statements, everyday conversation and on TV talk shows.
