who versus who and why?
Strangely, the latest issue of one of the magazine news-weeklies, Time Newsweek USNewsandWorldReport, has a cover story with the provocative battle of “Lincoln Versus Darwin”. This strikes me as a contrived battle — I don’t particularly see how Lincoln and Darwin or Lincolnism and Darwinism are mutually exclusive.
Other battles to take note of: Comstock versus Edison.  Friedan versus Dewey. Walker versus Trump.
I don’t quite know where these battles would take us and what criteria you would use to judge the victor, but there you go!
