I really wouldn't have a problem with a person's age except for two reasons.

1. Obvious health reasons. More likely to die from an illness, could drop dead at any moment from a heart attack, etc.

2. The older a person gets, the more set in their ways they become. This is a double edged blade. It's good because we'd have a leader who is steady and willing to continue on with the plans they make. However, being set in your ways is NOT a good thing when it isn't benficiary to the country.

All in all, I'd rather NOT have an old man for president, but I'd pick him in a heartbeat over Clinton.
