In America, we get the government we deserve. So if we elect Mitt Romney, we'll get this.

According to ABC News, Romney, a former executive at private equity firm Bain Capital who is projected to be worth upwards of $250 million, holds around $8 million of his personal wealth in as many as 12 funds based in the Cayman Islands. Romney also lists a separate investment, valued between $5 million and $25 million, placed on the same Caribbean island chain.
ABC News reports that Bain holds some 138 shrouded offshore funds in the Cayman Islands alone. Romney's campaign has maintained that such behavior is not unusual, and that Romney himself has paid all the appropriate U.S. taxes on his holdings within the accounts.
From ABC News:

Tax experts agree that Romney remains subject to American taxes. But they say the offshore accounts have provided him -- and Bain -- with other potential financial benefits, such as higher management fees and greater foreign interest, all at the expense of the U.S. Treasury. Rebecca J. Wilkins, a tax policy expert with Citizens for Tax Justice, said the federal government loses an estimated $100 billion a year because of tax havens.

Reuters reported earlier Wednesday that Bain also held accounts harbored in places such as Bermuda, Ireland and Hong Kong, which could lead to further questions about Romney's personal involvement in these holdings.
