Summary of GOP primaries :
Due to President Clinton's high approval rating , many prominent Republicans who were expected to run in 2000 decided not to run .This included Texas Governor George W Bush , who most pundits expected would run in 2000 , and likely would be the GOP nominee if he decided to run. Due to Governor Bush not running , the GOP field was wide open .Despite the field being wide open, by the Iowa Caucuses it became clear that the GOP primary front runners were Senator Phil Graham and Senator John McCain, and the closeness of their primary rivaled the 1976 GOP primaries and with the same result . Like in 1976 the more centrist candidate would barely beat the more conservative candidate .
