To Mitt or Not to Mitt by @DavidOAtkins

Mitt Romney’s campaign released hundreds of pages of tax documents on Tuesday morning, providing an inside glimpse into his sprawling investments, both in the United States and abroad, in an effort to dampen the attacks on his wealth that have become a central focus of the Republican presidential nominating battle.

Mr. Romney and his wife, Ann, had an effective federal income tax rate in 2010 of 13.9 percent, paying about $3 million in taxes on an adjusted gross income of $21.6 million, the vast majority of it flowing from a myriad of stock holdings, mutual funds and other investments, including profits and investment income from Bain Capital, the private equity firm Mr. Romney retired from in 1999.
