Two party system

The two party system is maintained by two forces. First each has a strong grass roots organization and second they provide a means for collecting money. Some have suggested that their stronghold on US politics may be threatened by the Internet. It is possible and some say likely that a very popular person with a large Blog following could collect money and spread ideas and become a viable candidate. As an example think of a person like Steve Jobs who has great name recognition and popularity. If a person like that had political ambitions chose to run an Internet campaign could they bypass the parties?
