Hillary Clinton did get around to releasing her 2000-2007 tax returns. Yes, she and Bill made gobs of money, but apparently they gave gobs to charity (albeit to the Clinton Foundation) and paid gobs in taxes. Isn’t this a non-story?
Among her many tales, she never pled poverty (or grumbled about summer camp fees for Chelsea) so I see no reason why this should matter. And in the walking-the-walk department, her charitable donations (9.5% of income, with some variation year to year) stack up quite favorably against her opponent.
So barring further revelations, I don’t quite see why she waited so long to release her returns. Like many things related to the Clintons, you wonder why transparency and honesty isn’t the first, rather than last, option.
