2004 Tennessee Republican presidential primary

The 2004 Tennessee Republican presidential primary was held on February 10, 2004, along with primaries in Arkansas and Oregon. Voters chose the state's 52 pledged delegates to the 2004 Republican National Convention.

Incumbent president George W. Bush won the primary and all of the state's delegates.

Procedure
Tennessee was allocated 55 delegates to the Republican National Convention: 52 were allocated based on the results of the primary, with the other three being unpledged superdelegates.

12 delegates were assigned statewide while 27 were assigned to the state's nine congressional districts, with three delegates per district. The delegate allocation rules for both statewide and district delegates were the same. A candidate would win all the delegates if they won a majority of the vote, but if the candidate with the most votes won less than 50%, the delegates were awarded proportionally based on the popular vote with a 20% threshold to qualify for delegates.
