From the article:
"As for the money floating the blimp, Collette and Smith have developed a detailed business plan carefully structured to avoid Byzantine campaign finance laws. They shunned traditional mechanisms such as creating an independent non-profit group under section 527 of the IRS code — like Swift Boat Veterans for Truth and the other groups that spent millions on ads in 2004 — or a political action committee — like EMILY’s List. Instead, they went an almost unheard of route, establishing a for-profit company: Liberty Political Advertising. The name is a nod to Paul’s ideology and the website boasts the “legal arrangement offers the best of both worlds: no limits and virtually no regulations.” In other words, very libertarian. Instead of soliciting donations like a PAC or a campaign or a non-profit political group, Liberty says it’s “selling political advertisements that you can sponsor.” By Friday evening, Liberty had pulled in nearly $150,000. Each payment will fund a portion of the $350,000-a-month blimp rental fee and associated costs ($10 pays for 1-minute’s worth of advertising on the blimp, while $1 million buys 10 weeks, according to the website)."
