Many states are still jockeying to be first in the Republican race to pick a candidate for the White House.

Iowa Republicans have now decided to hold their state's presidential nominating caucuses Jan. 3.

The state's Republican chairman, Matt Strawn, said a Jan. 3 caucus "provides certainty to the voters, to our presidential candidates, and to the thousands of statewide volunteers" in Iowa.

The news follows a chain reaction of early-voting states trying to preserve their lead-off status.

In September, Florida moved its primary to Jan. 31.

Now New Hampshire is threatening to move its primary into December.
