The 2008 Republican primaries were the selection processes by which the Republican Party selected delegates to attend the 2008 Republican National Convention. The series of primaries, caucuses, and state conventions culminated in the National Convention which was held in Saint Paul, Minnesota, September 1–4, 2008, where the delegates voted on and selected a candidate. A simple majority of delegate votes in September (1,191 out of 2,380) was required to become the party's nominee; estimates based on delegate pledges had John McCain surpassing this total after the March 4 primaries in Ohio, Rhode Island, Texas, and Vermont.
