Had John McCain won the Republican nomination in 2000 and served eight years as president, what would the 2008 Republican Party Presidential Primaries be like without him (assuming his vice president rules out a 2008 run)? I could see Giuliani and Thompson doing much better, but will it be enough to win them any states? Does George W. Bush return eight years later like McCain had OTL? If not, does Mitt Romney become the front runner?
