Several Democratic senators are separating themselves from their leadership and encouraging President Obama to cut Social Security benefits by raising the retirement age in order to keep the entitlement solvent. Sens. Tom Carper (D-DE) and Sen. Dianne Feinstein (D-CA) and Sen.Joe Lieberman (I-CT), who caucuses with the Democrats, are all openly calling for reform, and making it plain that the party is disunited on the issue when a titanic debate over debt is gathering momentum. If the president called for raising the Social Security retirement age by a year or two, phased in slowly over several decades, these senators say they could support him. But Senate Majority Leader Harry Reid (D-NV) refuses to give an inch on benefit cuts, arguing that the program has not contributed "one penny" to the debt.
