Idaho's Republican presidential primaries, held traditionally in May, had little to no impact on who the standard bearers would be. But Idaho's Republican State Central Committee has voted to shift from a primary system to a caucus and to move the event to March, so that the Gem State can be a part of the so-called Super Tuesday. Idaho's caucus will be allowed to be held on the earliest Tuesday allowed by the Republican National Committee. Only four states have announced caucuses or primaries earlier: Iowa, New Hampshire, Nevada and South Carolina.
In 2008, Super Tuesday included 24 state primaries or caucuses. No word yet if the Idaho Democratic State Central Committee will move its caucus to an earlier date.
