"As emotions run high over the law, anger and fear about its impact on Medicare could be a deciding factor in some particularly close congressional races, especially in areas where there are large numbers of seniors, say political analysts such as Robert Blendon, professor of health policy and political analysis at the Harvard School of Public Health. 'It could make a difference in any one of these races,' he says.
Republican candidates across the country are pummeling Democrats with the claim that the new law would gut the program by cutting $500 billion. Democrats accuse Republicans of distorting the truth: They say the law will only slow spending, at the expense of hospitals and insurers — not seniors.
In reality, while the new law will save the government $533 billion over the first 10 years, Medicare spending will continue to grow annually, at about 5.5% instead of 6.8%, based on Congressional Budget Office spending data." Source
