'Trump can barely speak in coherent sentences, let alone know all the complicated machinations of the U.S. tax codes.'
Trump has no need to know all the tax codes. Thats what his lawyers and accountants are for. I have no doubt Turnbull, Shorten and Clinton also practice legal tax minimisation sttategies available.to the wealthy.
BUT Hillary according to the FBI, as a former Presidents wife and now Secretary of State did not know until very recently that a 'c' on an email meant it contained classified information... sent c info around using an unprotected server she had in her basement and a personal email account.
Hillary can talk, but she's a stage managed actor and sold out puppet.
