A Democratic super PAC backing President Barack Obama's re-election and an environmental group are airing $1 million in advertising in Colorado and Nevada seeking to tie Mitt Romney to oil companies.
The ad by Priorities USA Action and the League of Conservation Voters Victory Fund casts the likely Republican presidential nominee as the "$200 million man," accusing Romney of supporting oil industry profits and tax breaks. It asserts that Romney is "in the tank for big oil."
Priorities USA Action is a super PAC founded by two former Obama White House aides. It has struggled in fundraising compared with Republican-leaning super PACs like American Crossroads and its nonprofit arm, Crossroads GPS, which have raised $100 million this election cycle.
