Could modern medicine have saved Lincoln?

This article from the Post describes what the doctors did for Lincoln in the 19th century and how treatment would be similar/different today. As the author points out, the doctors attending to Lincoln followed many of the same protocols as modern EMTs and doctors. And the author poses the question, how would our world have been different if Lincoln had lived? Even if Lincoln had lived with decreased motor function and a drastically decreased ability to communicate, inevitably his survival would have changed a great deal about the course that history has taken since the Civil War.
