Colorado’s largest cities have caps on campaign contributions now that Aurora has made changes

Aurora will soon impose strict limits on how much money can be raised in mayoral and city council races, becoming the latest large Colorado city to reform a campaign finance system that many decry as too opaque and friendly to big business interests.

With Aurora joining Denver, Fort Collins and Lakewood in revamping its rules on the role of money in local races, four of the state’s five most populous cities — encompassing nearly a million registered voters — will have campaign finance controls on the books.

Colorado Springs puts no restrictions on contributions to candidates running for public office.
