The GOP and Democratic political conventions are finally upon us. They will be scored by the media for tone and how well each side makes its case to Americans. No sooner will the gavel end these proceedings for campaign 2016, then those of us in the public opinion community will try to measure how the public reacted. But, beware the post-convention bounce. If history is any guide, there is no guarantee that there will be a significant change in the presidential contest as a result of the conventions, or that it will be long-lasting. CONT.
