The most accurate poll is the vote, the republicans run on changing the system and win the old people’s vote.
Democrats fight that change and win the young people’s vote.
I would worry more about the people voting against your agenda , rather than about the people voting with you.
Sure the oldsters vote with Republicans, that’s good. I’ll give them credit for that. But when Republicans get to Congress and actually start proposing Social Security reforms, the reforms go nowhere in committee or on the floor, due to strong opposition even from their own party. The oldsters make their voice heard. NO!
That’s why NOTHING has happened on Social Security for many years, since Reagan was in office and raised the retirement age quite gradually.
