Just as a point of information, Doc. The DNC and RNC have very little influence on presidential primary campaigns, especially so on who should or shouldn't run. Their primary ability is financial and they don't usually give money in primaries. They do have impact in setting the ground rules for primaries but even there their influence is muted by the states. They have much more impact on general election campaigns and on congressional races, where they can give a lot of money.
Modern individual presidential campaigns are pretty insular. They do more or less what they want and what they think will help them attract votes. Pretty sure the Obama campaign in 2008 looked at the DNC the way Apple looks at GM - future road kill.
