There is to much power in the office of president for there to be anything secret. Especially a tax return. The president, whether or not there is a D or R by their name, should be force to disclose their tax returns. Some people take capitalism to far, such as the US citizens who sold supplies and business machines to Hitler and force laws to be past that we can't sell supplies to countries that we have declared war against. Actually, that law should be expanded to countries where we have troops at or have air and drone strikes against, declared war or not.
