Yes, while the newsletters are potentially damaging, especially the way the media is twisting things, they are a wildcard that is being played early in the election cycle to try to stem RP's win in Iowa. Now that they are played, any rehashing of them as time goes on has a reduced effect. In addition, as some of the media distortion comes to light (such as the interview on CNN that was selectively edited), the introduction of the newsletters lose some of their impact. Yes, there will be many people who will not search out the facts and will believe RP to be racist. However, if you recall, Obama also had his tussle with such things and was able to rise above them. I expect RP to do the same and see the media's involvement in introducing them early on in the process as a desperate move that prevents them from doing so later with any real effectiveness. What else will they try to do to discredit him? It won't be dishonesty, marital infidelity, bribe taking, cronyism, influence peddling, etc.....all the normal things that potentially could trip up other candidates.
