Thanks for your response. You've made me re-think my response a little bit. When I said that I didn't think that the internet presidential politics, I mean that it would not be able to turn a fringe candidate into a mainstream candidate. However, I do believe there are other ways to have a large impact on an election without dramatically changing percentage points.

For example, if Barrack Obama does earn the Democratic nomination, it will be because of his internet campaigns with younger voters. What I mean to say is that a mainstream moderate might be able to beat another mainstream moderate in an election because he or she has a better internet marketing campaign that puts him or her over the top. The difference resultant from an internet campaign might be a meager 4 percentage points, but less than a single percentage point can swing an election as we've all seen in 2000. In that case, the internet could have a huge impact.
