We know (and economists know) that people respond to incentives. There are numerous examples in all fields and googling it will bring up all kinds of examples.
Now we know that Ron Paul wants to eliminate the personal income tax. How much money would this give back to the average American? Ron Paul, in the next debate performance, should announce that if he is elected President, every person in America will get back $100 (or whatever the figure turns out to be). He can then make it more personal and contrast the other candidates in that it is not clear what will happen if any of them are elected, and then he can use it to segue into how his plan will stimulate the economy and get more jobs.
