Why, if Romney was Governor of a state, does he not understand - - -?

Romney says Emergency.Disaster response should be the responsibility of the states and done under control of the governor. He was saying FEMA should be abolished BUT now he is saying they are important but should have a limited role in disaster relief.

He was a governor so he should know how FEMA works.

Emergencies and Disasters are manged at the lowest possible level. A community is responsible for their disasters. If they can not handle it the county is asked to assist, If the county needs assistance they go to the Governor who provides states assistance. If it is too big for the state they can ask for federal assistance and FEMA will respond; the governor is still responsible for controlling the situation as we are seeing in the current East Coast disaster.

FEMA can respond without request when disaster involves fedralproperty and they will respond when a disaster is so big it involves several states; but - the governors are still responsible for the activities within their states. FEMA provides advice, subject mater experts, labor, equipment, funds and virtually any resources needed to assist the local and state governments.

Why does Romney not understand the role of FEMA and not knowing why would he suggest abolishing FEMA without finding out what their role is?
