DesignBay have a very interesting study of presidential campaign logos over the past few years. The results of this study can be used to analyse the logo designs of other 2008 presidential candidates, and gain an insight into what makes good logo design and what should be avoided.
This study seems very biased to me. The writer obviously did not understand why the blue and yellow colors were chosen by the McCain camp for their campaign. The colors are representative of his time served in the US Navy.
thanks...
