President Obama’s re-election campaign is launching a new offensive against Mitt Romney, hammering the former Massachusetts governor for keeping his money in foreign bank accounts.

The campaign’s new ad, “Swiss Bank Account,” accuses Romney of shipping jobs overseas while he worked at Bain Capital and of outsourcing government jobs to India while he was governor.

“It’s just what you’d expect from a guy who had a Swiss bank account,” the ad concludes.

The ad will air on broadcast television in the crucial swing states of Iowa, Ohio, and Virginia.

Meanwhile, Obama’s campaign website has posted an infographic which shows all of the overseas locations of Romney’s money according to Mitt and Ann Romney’s 2010 tax returns.
“We don’t know if he’s using these accounts to avoid paying his fair share in taxes,” the website warns, “but we do know that in 2010, Romney’s tax rate was a startlingly low 13.9%…tell Mitt Romney: Bring your offshore accounts back to the USA.”

When Romney’s tax returns were released in January, they helped contribute to a huge slide in the polls that threatened to derail Romney’s campaign. Until Romney proves that he has a convincing response to criticism about his offshore accounts, don’t expect the Obama campaign to let the issue die.
