Slide by slide, Romney ticked through 20 mistakes, from Obama’s “Middle East apology tour” to the president’s lack of support for Iran’s green revolution to the administration’s infamous “reset” with Russia.

“With all that bad news, is it not true that arguably President Obama is the worst foreign policy president in history?” Romney asked. “I think he is.”

Next came the slides about Obama’s first-term secretary of state, Hillary Rodham Clinton, the Democratic presidential front-runner. First, Romney showed a map of the globe, colored in for all the countries she visited.

Then he mocked her.

“Secretary of Schlep,” the next slide read.

“She was everywhere,” Romney said, but he insisted she made “mistake after mistake after mistake.”
