Anything helps. Even $5. Personally, I love seeing small donations.
I honestly didn't think it through much at all. His performance made me want to donate to him, so I just tailored the moneybomb idea around that with the chance others agreed. Tonight, I saw a Ron Paul who was taking our advice, being more aggressive, boasting a bit, and just plain ol' fighting for our liberty. In a way, I look at my donation tonight as a payment to Dr. Paul for working so hard for me and our country--with the added benefit of him becoming our 45th President.
