I came across a refreshing usage at work last night.
Mark Rozell, a professor of political science at George Mason University, said the similarity of the attacks suggests a concerted effort to "build a picture" about Obama's character before the political newcomer has a chance to convince people of the truth of his rhetoric.Yes! For once, concerted means "concerted"! The story was about various McCain operatives working together, in concert. That's right: To make a concerted effort, despite widespread usage, isn't to try really, really hard to do something. That would be, perhaps, a determined effort.
Even the notoriously permissive Merriam-Webster's dictionary doesn't accept the "trying rully, rully hard" definition.
