Follow the money
Clinton campaign disclosures reveal that 316 lobbyists and corporate PACs have donated more than $600,000 so far to put Hillary in the White House. The number of contributors — more than double runner-up Jeb Bush's 140 lobbyist backers — makes Clinton the clear K Street favorite for 2016.
While the Obama campaign in 2008 and 2012 refused donations from registered lobbyists as part of a poorly kept promise to limit lobbyist influence in the administration, Clinton has long been noted for her ties to corporate interests, particularly on Wall Street. "[T]here is a list of people who are very committed to her from eight years ago," said Al Motteur, a lobbyist who is bundling donations for Clinton.
At the other end of the spectrum, Bernie Sanders, one of Clinton's rivals for the Democratic nomination, took in just $420 in lobbyist donations, while Republicans Carly Fiorina and Rand Paul received the least K Street support on their side of the aisle.
