Leaving your wife and hyping science will do this to a fella:

A new Gallup poll finds plummeting approval ratings for former Vice President Al Gore, who recently announced a separation from wife Tipper after 40 years of marriage and now faces allegations that he committed sexual assault in 2006.
Half, or 49%, of Americans now view him unfavorably while 44% see him favorably. In 2007, just after he won the Nobel Peace Prize for his work in fighting climate change, 58% held a favorable view and 37%, an unfavorable one.
The current ratings are the lowest since Gore, the Democratic candidate for president in 2000, asked for a recount of Florida’s election results that year. His disapproval rating then was 52%.
