Al and Tipper Gore Seperates After 40 years of Prince, Bush and The Internet

After 40 years of marriage which including a lost presidency for former Vice President Al and Tipper working with the Parents Music Resource Center to censor Prince back in the 1980's, The  Gores has called it quits. 

The splitting couple said in an email "a mutual and mutually supportive decision that we have made together following a process of long and careful consideration."

Isn't it funny that Gore's with the "stable" marriage are breaking up, but Bill Clitnon with all of his indescretions is still chugging along with  Hillary ?

This brings up a question: What's the longest marriage you know of couples under 60 years old?
