This is a scenario that personally intrigued me for a long time and wanted to look into further.
ITTL, Former Massachusetts Governor Mitt Romney wins the nomination in 2008 during the Republican Party Presidential Primaries, but is defeated in November during the General Election by New York Senator Hillary Clinton.
With Romney's defeat in ATL 2008, the 2012 Republican field is cleared and President Clinton faces one of two Southerners in November, either Former Arkansas Governor Mike Huckabee or Former Speaker of the House Newt Gingrich. How might the General Election turn out against either of them? What effect might this have four years later during the 2016 Republican Party Presidential Primaries?
