Do We Have The Right To A Non-Dementia President?

 No.  You don't have such a right, and I would seriously question how you'd write this 'right' into the Constitution.

You also don't have the right to a non-dementia Supreme Court Justice, House member or US Senator.  You don't have the right to non-dementia IRS managers, non-dementia State Department folks, or non-dementia CIA/FBI agents.  

When you get down to it.....you don't even have the right for a non-dementia muffler-repair technician, non-dementia coffee shop manager, or non-dementia bank clerk.

The current estimate (by the CDC) is that around 5.6-million Americans over the age of sixty....have some developing or full-scale episode of dementia.  If you do the statistical game.....the numbers are two women having a form of dementia....to every single guy.

The odds that at least one Supreme Court Justice has some developing signs of dementia?  Probably better than 50-percent.

The odds of three US Senators having some developing signs of dementia?  Probably better than 50-percent.

You can talk about this as much as you desire....but you don't have a right to non-dementia people being in responsible positions.
