Sen. Clinton has been trying mighty hard to make the primary season a referendum on the difference between words and deeds, but as tonight's results show - that contrast is falling flat. Taking her baton, John McCain is now calling Senator Obama's rhetoric "empty". Coming from the guy who is running to add another term to the empty Bush presidency, that's rich. But even moreso, it doesn't work. If the choice is McCain's pedestrian, ancient rhetoric with a history of right-wing advocacy versus Obama's oratory and progressive change - well, it ain't even close.
