Some are now saying that the comparison of Sen. Obama to President Kennedy is bad, based on the details of Kennedy's presidency. Who are these people? Seriously. Who the heck are they? Is it any wonder Dems lose elections based on these sort of Excel-spreadsheet analysis of public sentiment.
President Kennedy is historically seen as the optimistic leader, slain in the prime of his life and the mystical force behind sweeping changes that came to America.
This is a gut reaction, not one tabulated by weighing numbers on a scale. This is how people think, this is how they make these decisions. President Clinton learned this and used it well. Other progressives should learn and put their slide rules away.
