Why won’t Mitt Romney make his tax returns public? – CSMonitor.com http://www.csmonitor.com/USA/Elections/From-the-Wires/2011/1026/Why-won-t-Mitt-Romney-make-his-tax-returns-public

Why won’t Romney do it? Speculation, from liberal group ThinkProgress and others, is that Romney pays a way lower tax rate than many Americans because of his extensive financial investments, from which income is typically taxed below that of regular income. One left-leaning analyst speculates Romney paid an effective tax rate as low as 14 percent on his $6.6 million to $40 million in income. (The range is so wide because of the imprecise nature of Romney’s very limited disclosures.)
