Minnesota Gov. Tim Pawlenty
Minnesota Gov. Tim Pawlenty is another green-leaning Republican state leader. He founded and co-chaired the National Governors Association's Securing a Clean Energy Future task force along with former Kansas Gov. (and Democrat) Kathleen Sebelius (now serving the Obama administration as Secretary of Health and Human Services) and he led talks among 45 state leaders to develop programs to reduce greenhouse gas emissions. While Pawlenty isn't afraid to appeal to the base every now and then — he backpedaled on the idea of a cap-and-trade system while on the Glenn Beck program and argued that humans didn't have much of an impact on global warming — it's important to remember that at least he was for it before he was against it.
