I worry less about him in this role, than the fact that it is likely (due to the present circumstances) to be a high-profile position, that an ambitious guy like Ridge will be able to use to further his Presidential aspirations.
He will likely do a very good job in this position, and unless Congress passes some really silly laws creating new powers not already granted by Congress by law to the executive branch, then it should not be a case of government creep.
But I thought when Bush bypassed Ridge for the VP nod, that was the end of Ridge as a potential future Republican Presidential candidate. I fear this gives his ambitions new life, and this is a man who has said that he believes being pro-life means that you want to force women to be incubators for nine months against their will. Any politician who thinks like that, who values life like that, is not someone I want to give any pathway towards the Presidency.
