Ummm.. that would be a yes. If Joe claims that he will be unable to buy the business because his taxes will go up too much, (which is exactly the claim that first he, and then McCain made) then yes it obviously blows their argument to hell when you find out that the most he will be cost is $900.00 a year.

Combine that with the fact that there is no way that the business actually brings in anywhere near enough to NET $250,000 which means that if anything the business will see LOWER taxes, then yes it very clearly does sink any validity that his question and McCain's argument had.
