Mitt Romney has every right in the world to keep his tax returns private, but not as a Presidential candidate. To some, Americans may appear to be going too far, but not to me. In Canada and other mature parliamentary democracies, politicians disclose assets, liabilities and income to a "conflict" commissioner, not to the public. Summaries are available but details are not and tax returns are not disclosed to anyone. Full disclosure should be required. For every politician.
