I doubt any President will ever not renew a state of emergency unless power to do so is taken from them by Congress or the Supreme Court. Never-ending "emergencies" were the reason for a bill passed in 1976 that specifically limited Presidential power to declare and continue states of emergency (it appears the Patriot Act supersedes that law now, or at least part of it).
"If ye love wealth greater than liberty, the tranquility of servitude greater than the animating contest for freedom, go home from us in peace. We seek not your counsel, nor your arms. Crouch down and lick the hand that feeds you; May your chains set lightly upon you, and may posterity forget that ye were our countrymen." -- Samuel Adams
