Over the last two years, Congressional Republicans have forced a 43 percent reduction in the primary FEMA grants that pay for disaster preparedness. Representatives Paul Ryan, Eric Cantor and other House Republicans have repeatedly tried to refuse FEMA’s budget requests when disasters are more expensive than predicted, or have demanded that other valuable programs be cut to pay for them. The Ryan budget, which Mr. Romney praised as “an excellent piece of work,” would result in severe cutbacks to the agency, as would the Republican-instigated sequester, which would cut disaster relief by 8.2 percent on top of earlier reductions.
