Public Campaign’s blog highlighted a National Journal cover story about super donors —  lobbyists who max out on personal contributions to political campaigns each year. In this election cycle the aggregate contribution limit is $108,200. 

Most of these K Street "royals" have spouses giving them the opportunity to double that amount (as long as the spouse goes along). Now that adds up to some real money as you will see. National Journal  includes a list of the top 20 individual K Street donors provided by the Center for Responsive Politics, as well as a deeper profile of five of the. Even though the report finds that the top lobbyist donors cite various motivations for giving, "virtually all of them enjoy a level of influence and access that many others on K Street would envy." 

And surprise surprise! K Street work has paid off spectacularly well for these folks.
