Mitt Romney’s campaign is already up with a response to an attack from President Obama’s campaign on Romney’s time at Bain Capital.

While the two-minute Obama ad, released this morning, focused on Bain Capital’s acquisition and handling off GS Technologies steel mill, the Romney campaign’s new ad, titled “American Dream,” focuses on another steel company Bain guided — Steel Dynamics.

“Steel Dynamics started with an empty field and a big dream,” the ad begins, before one employee labels the company “a perfect entrepreneurial story.”

Later in the ad, the narrator notes that Romney’s “private sector leadership team stepped in” when others passed on the project.

Romney has repeatedly been attacked in this campaign as a corporate raider — one person featured in the Obama campaign compared Bain to a “vampire” — and his campaign appears to be more than ready to respond to the looming attack as the general election heats up.
