The National Committee to Preserve Social Security and Medicare, an influential nonprofit advocacy group for seniors, is endorsing U.S. Senator Brian Schatz in the Democratic primary for U.S. Senate. The group made the announcement today. Schatz has made protecting Social Security an issue in the primary against U.S. Representative Colleen Hanabusa, who has countered that she too wants to defend the entitlement program. The congresswoman has said that Schatz is needlessly scaring seniors at a time when cuts to Social Security have fallen out of favor as a deficit-reduction strategy.
