Actually . . . no. As long as liberal young people survive into adulthood conservatives won’t die off.
People become more conservative as they grow older.
The old saying goes :
“If you’re not a liberal when you’re young, you don’t have a heart. If you’re not conservative when you’re old you don’t have a brain.”
This contains a lot of truth. If you’re not an idealistic youth, you don’t have a heart. If you haven’t noticed the consistently awful results of government programs. You don’t have a brain.
