TOPEKA, Kan. — Republican presidential candidate Ron Paul is calling Kansas "a fertile field" as he pitches his libertarian views the day before state caucuses for delegates to the party's national convention.

Comment on this story

The Texas congressman told about 500 people at a downtown Topeka rally on Friday that he doesn't have a particular number of delegates in mind but, in his words, "the more the merrier."

Kansas has 40 delegates up for grabs in Saturday's caucuses, which will be held at 96 locations around the state.

Kansas Gov. Sam Brownback met with Paul before the rally and then joined former Pennsylvania Sen. Rick Santorum at another Topeka event. Brownback endorsed the bid of Texas Gov. Rick Perry before he suspended his campaign in January.
