Republican businessman Dave Spence has kicked in more money in his quest to become Missouri governor.
Finance reports show Spence supplied an additional $500,000 to his campaign Monday, raising his total amount of self-financing to nearly $3.3 million.
A couple of other Republicans seeking to challenge Democratic Gov. Jay Nixon also have been spending their own money for the Aug. 7 primary.
Finance records show businessman Fred Sauer has given his campaign an additional $205,000 this month, bringing his total self-financing to about $423,000.
Attorney Bill Randles loaned his campaign an additional $7,700 during the first few weeks of July, raising his amount of self-financing to nearly $56,000.
Nixon faces no significant opposition in the Democratic primary. He has more than $7 million in his campaign account.
