The astounding divorce declaration from Al and Tipper Gore has made people unhappy who know them, but peers and specialists say that there were slight cracks in their wedding, which were not difficult to overlook.

The two had jointly endured the near-death of their son in a 1989 car mishap, Gore's vice-presidency, his loss of the presidency to Florida's infamous chad ballots, and then his resurgence as an ecological campaigner.

But as their marriage touched the 40-year score, their courses and hopes deviated, ex-Gore Campaign Manager, Tony Coelho said.

He said, "She went and did her thing. She was supportive, but she didn't share the world stage with him".

Today, ABC News Analyst, Cokie Roberts told "Good Morning America" that the pair's declaration on Tuesday caught her off guard.

She said that it's depressing, they were good people.

Roberts said that she believes that the wedlock's firmness through the more tricky years gave the Gores a mutual goal that might have squandered when life started to decelerate.

She added that though Al Gore's recreation as a Nobel Peace Prize-winning ecologist has resulted in a lot of awards, he ultimately has to come home where "his wife knows he puts his pants on one leg at a time".
