Do you think Ronald Reagan would have proposed these same programs to rebuild a great American city?
No. The question is sort of moot though as Reagan was a great conservative but he is the definition of conservatism.
A conservative would give the federal government's assistance in emergency situations and then provided low interest loans to businesses, and state and local governments to rebuild.
A true conservative would not use the police power of the state to confiscate money from those who don't even live in the area and then give it people who were irresponsible enough to live in a very flood prone area and not buy flood insurance.
This won't end with Katrina. How about the next hurricane, earthquake or flood? The federal government has now set a precedent of being an ATM for anyone involved in a natural disaster. That is what insurance is for.
What do you think that liberals are going to do with this precedent when they are in charge? They will find ways to say that 'poverty' or 'racism' is a 'natural disaster' and use that as an excuse for even more wealth transfer.
