Jonah, I hate to say it but I have to disagree with you. Romney presented a plan and goals in his speech. He's made it clear he wants change by picking Paul Ryan. He's presented white papers, though those obviously don't get out much. The man has a plan, I really don't see where you get this "no ideas" thing from.
Are they trying to appeal to moderates? Yeah, and personally I don't see how that is a bad move. Romney pretty well has the base locked up at this point. I know after watching the RNC I'm certainly more stoked for the election and voting for Romney, even though there wasn't a ton of red meat. End of the day, this election is likely to be decided by those moderates and independents.
