Ron Paul's "Campaign for Liberty" - Why?

Being a believer in the principles and liberties on which the nation was founded, I have been supporting and following the Ron Paul campaign. Because I am on their mailing list, today I received a "Letter from Ron Paul" stating that he has now begun a "Campaign for Liberty" with it's own website, blog, and apparently - funding. I have read through the "Mission" page on the campaign's website. The principles and strategies laid out there seem to me to be strikingly similar to those of the Libertarian Party. Therefore, my question is "Why?" Why do we need another campaign for liberty? It would appear that we already have one that is organized with a presence in all 50 states and has even nominated its own candidates for President and Vice President of the United States, not to mention has won many local races in many states for county and state offices. My guess is that Congressman Paul has seen the decline in support and unity within the Libertarian Party and is determined to find another way to advance the ideals and principles of that party. Even with a former U.S. Senator as their candidate, the Libertarians are only polling 2%-7% of the vote. I believe that Dr. Paul is very aware of this and knows that he must grow a libertarian base within the Republican Party to effect real change in Washington, D.C. He knows that the chance of a Libertarian candidate ever being elected President are almost nil, but that there is a real possibility in pulling the Republican Party back to its platform. Only time will tell, but if Paul can succeed in helping more "libertarian" Republicans get elected to local, state, and national offices, he might see his very own R3volution realized.
