Topeka ? Kansas has a full field of candidates for its Republican presidential caucuses March 6.

The state Republican Party said Friday that eight candidates had filed. The deadline was Saturday, but the party said no other candidates’ campaigns had contacted it, and the Kansas GOP is charging a nonrefundable fee of $10,000 for candidates who want on the ballot.

The field filled out when former Minnesota congresswoman Michele Bachmann, former Utah Gov. Jon Huntsman and former Pennsylvania Sen. Rick Santorum filed this week.

They joined former U.S. House Speaker Newt Gingrich, Texas Gov. Rick Perry, former Massachusetts Gov. Mitt Romney and Texas congressman Ron Paul.

Georgia businessman Herman Cain also filed, but he has since asked to have his name removed from the ballot because he suspended his campaign.
