In 1992, Bill Clinton was 46.
Barack Obama is currently 46.
George H.W. Bush was 64 when he became president.
Hillary turns 61 this year.
Okay, so what's the point? Most presidental ranking opinion polls place Bush Sr. and Clinton in the middle of the pack (not great, not horrible -- just average) -->
How can that be? Bush Sr. had so much more "experience."
And check this out: Theodore Roosevelt is generally ranked as one of the top 5 best presidents. TR was just 42 years old when he became president, and I believe he had only 3 years of public service before assuming the role!
The bottom line: there's a reason the constitution says you only need to be 35 to be president.
Good judgement has much more value than mere experience (experience just means you're older, really, anyway). And "experience" isn't a synonym for wisdom.
