Why do Republicans hate old and disabled people?
As Kos notes, Sen. Bill Nelson offered a resolution expressing the sense of the Senate that "Congress should reject any Social Security plan that requires deep benefit cuts or a massive increase in debt." The final vote? The amendment was rejected 50-50, which means all but five Republican Senators are in favor of deep cuts in benefits and/or massive increases in debt above and beyond the yearly deficits we're already facing.
Let's focus on that last part and simplify it: Republicans want to cut your Social Security and put us even deeper in debt.
Howard had it right: if you want fiscal responsibility in Washington, you'd better elect a Democrat, because you can't trust Republicans with your money.
