Casting "Lincoln"

Spielberg's Lincoln: The full cast listing shows just three generals: Grant, Seth Williams and Ingalls. Seward, Stanton, Blair and Welles are the only cabinet members cast. Edward Bates has been replaced by telegrapher David Bates. There are four uncredited Radical Republicans (not identified) and eight members of Congress. Lots of Grover's Theatre, not much Ford's.

How strange.
