I don't think so. American voters overwhelmingly respond very effectively to negative campaigning, even as they condemn it. The way to do it, therefore, is to engage in it in ways that can never be traced to the candidate his or her self. Hence, the "527" was created (like that Swiftboat Veterans group), acting on behalf of the candidate and undoubtedly with his/her campaign's unofficial involvement and support, but always with a level of plausible denial.
Every year everybody runs smear adds and nobody seems to say if they both smear eachother than how are you to know who to vote for if they all corrupt,lie,steal. are their any hounest polititions out there i think not. we need a new system.
