Mike Huckabee won the Iowa GOP caucuses last night, a decisive victory that puts him at the front of the pack in the Republican presidential race -- that is, until the New Hampshire primary next week. Huckabee is one of just two GOP candidates who support a cap-and-trade system to fight climate change (McCain is the other), although Huckabee hasn't come out in support of any specific emission targets. In an interview with Grist earlier this year, Huckabee stressed the connection between his Christian faith and his drive to protect the environment.
On the Democratic side, Barack Obama was the night's winner. Like all of the other Democratic candidates, he's got an ambitious plan to tackle climate and energy issues, which he described in an interview with Grist this past summer.
