I did my taxes this past weekend, and had to laugh when I was presented with the opportunity to voluntarily pay a higher tax rate than I would otherwise have to (5.85 % instead of 5.3%):
You bet your sweet ass most people say no! I did some quick (read flimsy) research to see just how many people say no and turned up a page taking Kerry to task for not opting to pay the higher tax rate,
which also had the only numbers I could turn up. I think it was something like a tenth of a percent of taxpayers, netting the state something like $20k in extra revenue. Yay.
