Registered lobbyists and their employer campaign donations made up about 25 percent of what legislative candidates spent during the 2016 election. And most of that money went to House Republicans. Despite that lobbyist largesse, the GOP lost control of the House to Democrats, while Senate Democrats increased their margin. Lobbyists and their employers reported donating more than $2.8 million to candidates and political action committees in 2016. That brings their total for the 2015-16 elections cycle to nearly $4 million, with more than 90 percent of that money going to legislative candidates or partisan PACs.
