By JEANMARIE EVELLYMajor cutbacks in government spending, on both the local and federal level, have left several community centers in the northwest Bronx struggling to make ends meet this year.Mosholu Montefiore Community Center (MMCC) in Norwood, which runs dozens of after-school sites, a senior citizen center, and other programs serving more than 28,000 Bronxites each year, has been appealing to neighbors for donations over the last few months in an effort to keep the center afloat.“Bottom line, we are probably close to a million dollars in cuts,” said Executive Director Donald Bluestone. “We’ve been closing programs, laying off staff. It’s a serious problem.”MMCC relies largely on funding from legislators and government agencies that have seen their budgets slashed in the face of ballooning deficits. “The staff here didn’t have a raise last year, and we’re probably looking at the same situation this year,” Bluestone continued. “It’s just a very bad time.”The center is losing out this year on federal funding in the form of member items or earmarks — money provided by legislators to projects or organizations in their home districts — an act banned this year by Congress in an effort to cut back on spending.
