If we are talking Johnsons and not letting our minds go into the gutter, What about Lyndon Baines ?
In chronological order, not in order of worse to worser.
5) Lincoln - Invalidated states rights and only freed slaves in slave states, not northern slave states.
4) Wilson - Started the modern progressive movement
3) FDR - 'nuff said
3) Johnson - Great Society
2) Jimmah - King of sweaters, 55 mph speed limit and long gas lines.
1) Obama - All of the above wrapped into one.
