Very misleading title.
His prediction in November, 2003: “But if the economy recovers and jobs come back, then barring any terrible catastrophe abroad, George Bush is going to be re-elected.”
In 2000, he predicted Gore winning. He scores this as being correct because Gore won the popular vote.
In other words, since 1988, he has never predicted a Democrat loss.
... and he had predicted Gore in a landslide.
