Statewide results -- After Super Tuesday
The 2008 Republican presidential primaries were the selection process by which voters of the Republican Party chose its nominee for President of the United States in the 2008 U.S. presidential election. Senator John McCain of Arizona was selected as the nominee through a series of primary elections and caucuses culminating in the 2008 Republican National Convention held from Monday, September 1, through Thursday, September 4, 2008, in St. Paul, Minnesota. President George W. Bush was ineligible to be elected to a third term due to the term limits established by the 22nd Amendment. In a crowded primary of several prominent Republicans eyeing the nomination, former New York City mayor Rudy Giuliani was the early frontrunner. However, former Arkansas Governor Mike Huckabee won the Iowa Caucuses as he gained momentum just two months prior to the primary. Moderate U.S. Senator and former presidential candidate John McCain won the New Hampshire and Florida primaries. After failing to win in Florida, Giuliani ended his campaign. McCain ultimately won the nomination after winning most of the primaries on Super Tuesday. Former Massachusetts Governor Mitt Romney finished second in the overall delegate count.
