Huntsman's enviro stance is up in air

The GOP candidate has tried to distance himself from his past support of climate initiatives.

But he's also courting the middle, which suggests that he could come back to the controversial climate change policy if the economy improves. By doing so, Huntsman is running the risk of being seen as an Arnold Schwarzenegger-style Republican who will only antagonize many of the primary voters he would need to win the GOP nomination.
