Filing for Missouri’s Feb. 7presidential primary has closed with 10 Republicans and fourDemocrats on their parties’ ballots.

The GOP primary drew most of the party’s best-known candidates, even though the state Republican party will choose delegates to the national nominating convention through a caucus procedure starting in March. Republicans Michele Bachmann, Herman Cain, Jon Huntsman, Ron Paul, Rick Perry, Mitt Romney and Rick Santorum all signed up for the Missouri primary.

But former U.S. House Speaker Newt Gingrich, of Georgia, did not file before Tuesday’s 5 p.m. deadline. The Democratic lineup includes President Barack Obama and three challengers: Randall Terry of West Virginia, Darcy Richardson of Florida and John Wolfe of Florida. Libertarian James Ogle, of Sacramento, Calif., is his party’s only candidate.
