'Roswell Babies' in the Democratic Party

Here's an email naming nine prominent Democrats who were allegedly born nine months after the wreckage of a UFO was found near Roswell, New Mexico in 1947 (they're all the progeny of space aliens, get it?). Funny, if true -- which it's not. Only one of these politicians is a real "Roswell baby" -- Al Gore, Hillary Clinton, Bill Clinton, John Kerry, Howard Dean, Nancy Pelosi, Dianne Feinstein, Charles Schumer, Barbara Boxer. Can you guess which one it is?
The truth is out there...
