Republican presidential candidate Herman Cain has become the fourth person to file paperwork to take part in the 2012 Kansas GOP caucus.

The state party said Tuesday that Cain joined Texas Rep. Ron Paul, Texas Gov. Rick Perry and former Massachusetts Gov. Mitt Romney in completing the necessary documents.

Kansas Republicans will hold their caucus on March 10 to determine how the state's 40 convention delegates are apportioned to the candidates. Republicans who are registered by Feb. 17, 2012, may vote in the caucus.

Kansas officials say former U.S. House Speaker Newt Gingrich is preparing to file for the caucus ahead of the Dec. 31 deadline.

Democrats will hold their state caucus on April 14.
