Both candidates are past their sell by dates. I really think both candidates need to swallow their pride and submit to the usual battery of tests any 75 year old man or woman should undergo by a battery of independent physicians and psychologists .
Actually, I'll take it one step farther, all candidates, no matter their age, should submit these tests. We were lied to about FDR, JFK, and who knows who else. These folks are working for us and we have a right to know. HIPPA laws be damned.
