You showed me a Senator from many years ago, in a different position now, whose view changed. You changed or exposed nothing. It still will not convince voters to vote for somebody that might interrupt SS every 5 years in "automatic Sunset debates", while it is debated whether to keep funding the retirement program, that grandma was require to be in, and contributed to, without fail since teen years. We have seen the debt ceiling debate shut down the government. There is little doubt, we would see old people held for ransom.
Do or say what you want. By in large, nobody over or approaching 65 will go for it, and if they weren't one of the winners of the game, will think you are trying to cheat them. It is always a losing proposition to attack old people in mass. It continues to be the "Third Rail".
