Ad Hits Lobbyist Influence

Barack Obama has just rolled out an ad called "Take It Back" wherein he slams lobbyist influence in Washington and vows change if elected president. The Washington Post profiled the ad this morning, you can watch it here. What do you think? It's good to see the issue of influence addressed by candidates, though I hope the focus goes to the influence of campaign contributions etc. rather than a simplified lobbyists=bad argument.
