Perry: Romney and Obama are ‘carbon copies’

Rick Perry is doubling down on what will clearly be one of his key strategies heading into the Republican presidential primary: Tying Mitt Romney to President Obama.

Last month, Perry slammed Romney as "Obama-lite," a title he based on comparisons between the health care policies Romney pushed as governor of Massachusetts and Obama's health care law.

Today, the Texas governor is out with an attack ad trashing Romney and Obama as "carbon copies" when it comes to their positions on climate change and other environmental policies.

The criticism is based largely on a Wall Street Journal piece noting two former Romney environmental advisers are now working in the Obama administration.
