Separation of Church and State and Tax Exemptions

Edwards said he wants to restore regulations on the energy market to increase transparency, and end taxpayer subsidies for oil companies. He also would raise fuel-economy standards to 40 miles per gallon by 2016. He called for ethanol pumps to be available at a quarter of all gas stations and for cars sold after 2010 to accept either gasoline or biofuels.

"We need to stand up to the big oil companies to create affordable choices for regular families," Edwards said.

Dodd's Energetic Ad

Sen. Chris Dodd (D-Conn.) launched the third ad of his presidential campaign today in Iowa and New Hampshire, a spot focused on his energy plan that, among other things, would implement a corporate carbon tax.

The ad begins with a group of children singing "We've Got the Whole World in Our Hands" as they play with globes.

A narrator intones: "All the Earth's creatures are threatened by global warming. One candidate for president is doing something to stop it -- Chris Dodd. He's the only one with an energy plan that has a courageous corporate carbon tax to transform American industry." The commercial goes on to note that former vice president Al Gore -- the oracle on global warming -- called Dodd's plan "creative."
