Over 75% of voters want maximum age limit for elected officials, poll shows

This isn't about their values at all. You keep on mindlessly returning to your algorithm for evaluating candidates assuming that people can make a decision as to whether or not an old person is healthy. But we are living in the aftermath of people failing to make that decision.

If you don't believe this, you've failed a basic political awareness test. If you don't believe that Trump was unhealthy for this country and that a vote for him is a vote against our civilization, you've failed a basic political intelligence test.

Your model of how well people make these decisions is flawed, wrong, and irrelevant.

If what you care about [is] in fact [their] health then their age should be irrelevant.

This is wrong. Health and age are deeply connected. If you can't accept that, you're failing a basic biological intelligence test.

Hint: There's nothing about a 28 year old that would make them unfit to be President. But our society has made the decision to set an arbitrary line at 35. There is no reason not to set a corresponding arbitrary line at 65.
