Today, I emailed the following to both of the major parties' presumptive nominees (to suggest policies, go to http://my.barackobama.com/page/s/mypolicy and http://www.johnmccain.com/Contact/), who both trumpet a cap-and-trade system as their method of reducing carbon emissions:

I understand that it is almost never politically viable to propose a tax increase of any sort. However, a carbon tax (or gasoline tax) would be a much more economically efficient method of reducing carbon emissions than the propsed cap-and-trade system on your website. Why do you support cap-and-trade over a carbon tax?

The carbon tax proposal could be coupled with an income tax cut for the bottom half of wage earners with a revenue-equivalent of approximately three-fourths of the expected revenue from the carbon tax, with the last fourth going to either paying down the federal debt or giving incentives for alternative energy developement.
