The Kentucky money politics law was quashed after ruling in a US District Court found the law discriminatory. From a recent post on Ballot Access News by Richard Winger:

On June 6, 2017, U.S. District Court Judge William O. Bertelsman, a Carter appointee, struck down a Kentucky campaign finance contribution limit that discriminated in favor of the Republican and Democratic Parties, and against all other parties. Shickel v Dilger, e.d., 2:15cv-155. The law, sec. 121.015(3)(b), said that individuals could give $5,000 to a “caucus campaign committee”, which was defined as: “members of the following caucus groups who receive contributions and make expenditures to support or oppose one or more specific candidates or slates of candidates for nomination or election, or a committee: 1. House Democratic caucus campaign committee; 2. House Republican caucus campaign committee; 3. Senate Democratic caucus campaign committee; and 4. Senate Republican caucus campaign committee.”

Because the law specifically names Republican and Democratic committees, and gives them the ability to receive $5,000 contributions, the law is discriminatory. Individuals generally can only give $1,000 to a candidate for state or local office, so a $5,000 contribution limit for contributions to these Democratic and Republican committees is valuable.

Also look here for detailed info on donors. The Kentucky Center for Investigative Reporting had more info on donations in the state in the 2016 election:

The amount of individual contributions across Kentucky varied widely by county. Ten whole counties reported total donations of $1,000 or less to the presidential campaigns. Meanwhile, cash flowed from the state’s three most populous counties — Jefferson, Fayette and Kenton. Each big-county cash haul was heavily weighted to Clinton. Seven of the top 10 most generous counties gave a majority of cash to Clinton. In 12 smaller, rural counties, Clinton failed to garner a single dollar in contributions.

Ballot Access News UPDATE from Kentucky: “starting July 1, 2017, that candidate limit goes from $1,000 to $2,000, due to a bill that passed the legislature earlier this year”.
