Washington (CNN) - The news about Al and Tipper Gore deciding to separate after 40 years of marriage shocked Washington - and those who know them - into a kind of frenzy: How could this be? They have always been the genuine political couple. The ones who were affectionate and caring; the ones who had fun. The couple who dared to smooch onstage at a national political convention.
Al and Tipper were like Peanut Butter and Jelly. Always better together.
And maybe they were. And what we saw was true. And maybe now - because it once was true and isn't anymore - they've decided to split.
