TOPEKA, Kan. (AP) — Republican presidential candidate Donald Trump will be on the ballot for the Kansas GOP caucus in March.

The real estate magnate has paid the $15,000 filing fee to be on the party’s caucus March 5. Former Florida Gov. Jeb Bush and Ohio Gov. John Kasich are already on the ballot.

Trump has led the GOP presidential race in most national polls for several weeks.

His closest challenger is Ben Carson, who was visiting Topeka and Overland Park on Friday. Carson has not yet filed for the caucus.
