CCP: “As this Legislative Review explains, a Center for Competitive Politics’ survey of 2013 state legislative activity shows that nine states – Alabama, Arizona, Connecticut, Florida, Maryland, Michigan, Minnesota, North Carolina, and Wyoming – raised or eliminated various campaign contribution limits last year. Five states increased their limits by 100% or more, two more increased their limits by 50%, and one repealed its limit on direct corporate contributions to candidates.”
