A Republican-affiliated outside group is making a major ad buy to attack President Obama in six swing states.

In an ad called “Too Much,” Crossroads GPS attacks the administration over high gas prices. There’s $1.7 million behind the ad, which is airing in Colorado, Florida, Iowa, Nevada, Ohio, and Virginia.

“No matter how Obama spins it, gas costs too much,” the narrator says, faulting the president for “taking credit for other people’s hard work.”

Obama has cited the rise in domestic oil production. But it really should be credited to Bush administration policies, because government extraction plans take years to affect production.

Obama’s policy on gas prices is getting brutal reviews; only 29 percent approve of how he’s handling the problem. At the same time, Obama has avoided direct blame for the prices themselves.

Nonprofits like Crossroads GPS can only make issue ads about policy issues, so the ad asks viewers to call President Obama and ask him to “work to pass better energy policies.”

American Crossroads, the group’s affiliated super PAC, anticipates having over $200 million in the bank to help defeat Obama. The group plans to launch its major ad offensive for May through July.
