According to Stockman, W was a worse President than Wilson. It's the third sentence in the column.
"who was the very worst President in American history……..well, except for the last two."
As the current President's term is not up and his legacy not yet written, your article indicates that GW Bush, at the time he served and still today, was the worst President ever. Stockman had to go back 100 years to find one bad enough to even compare. Even worse than Woodrow Wilson.
That was your point....right? That we shouldn't vote for W's?
