Idaho was won by Republican nominee John McCain by a 25.3% margin of victory. Prior to the election, all 17 major news organizations considered this a state McCain would win, or a red state. Polling in the state gave a sizable lead to McCain over Democrat Barack Obama, with most polling predicting a McCain win of at least 30 percentage points. Despite his landslide defeat in the state, Obama over-performed his polls and greatly improved on Kerry's performance four years earlier. Idaho has not gone Democratic since Lyndon B. Johnson narrowly won it in 1964.
