A great piece by Joshua Green in the May issue of the Atlantic Monthly suggests "more Democrats appear to be coming around to the belief that -- election results be damned -- what they stand for may not be the problem after all." It's not new ideas they need, instead "a snazzy new sales pitch will revive their fortunes."
It's messaging, "the process of selecting words that impart to voters whatever sentiment the author is pushing," that will make the difference. "One famous example is the Republican effort to recast the 'estate tax' --with its implied application to landed aristocrats only -- as the much more menacing (and less discriminating!) 'death tax.'"
