In tonight's debate Kerry charged that Bush counted as a small business owner because he received $84 from a timber company. Bush claimed ignorance of this, but it turns out it's true. Factcheck.org has an article saying that he did get paid $84 from a timber-growing company counting him as a small business owner (Google Cache article).
Factcheck.org wasn't working properly when I found the article, so I had to use the Google cache article. The real article is here with a correction that they made on October 9, the day after I posted. It says that Bush does own the timber company, but the $84 came from an oil company. Either way, he would still count as a small business owner under his definition of what a small business is.
