Yes, it took along time to get aid to the people but I would say that both sides should share the blame and just be done with it. It's not a left or right issue, it's a matter of the government on a whole, failing the people. Not Republicans, not Democrats, but everyone.
How long has the levee system been inadequate? Far too long. It's not like the people of New Orleans just found out that they live below sea level. They live in an area where hurricanes are common and they should have been prepared for the worst. People can point their fingers at whoever they want but the fact of the matter is the entire government whether it be state, city or federal level, failed at preventing and taking the necessary steps of minimizing the destruction the hurricane caused. Not trying to be callous or take anything away from how horrible this is, because I am not. I actually volunteered my time and donated money to the Red Cross this weekend, but had they made an adequate levee system, then New Orleans would have not been destroyed to extent that it now is.
Before 9/11 the Federal Emergency Management Agency listed the three most likely catastrophic disasters facing America as: a terrorist attack, a major earthquake in San Fran and a hurricane in New Orleans. So why was New Orleans and the rest of the nation so unprepared?
