Ron Paul Campaign Contribution

I've been highly tempted recently to donate to the Ron Paul campaign. I have many reasons to do so:

• He's the only candidate that I believe when they speak.
• He's seems to have an understanding of the issues - and more in depth than any of the other candidates, or at least more understanding than they are willing to show to the unsophisticated masses.
• He will work to eliminate the IRS - my contribution could even be viewed as an investment in this light.
• He's the only one trying to make the country freer. Less interference and monitoring sounds good to me.
  
• Most of his other issues found at RonPaul2008.com
  
• I have more money than I really need.

So, you may be asking, "Why haven't you gone ahead and contributed, Mark?" I'm opening it up for comment first; I want to be sure I'm making a good decision. So I ask you: Why shouldn't I contribute to Ron Paul's campaign? Is there a more deserving candidate?
