I am not sure that many politicians are good on this score, but Hillary Clinton and Donald Trump are likely as bad as it gets on crony capitalism. Forget their policy positions, which are steeped in government interventionism in the economy, but just look at their personal careers. Each have a long history of taking advantage of political power to enrich themselves and their business associates. I am not sure what Cruz meant when he said "New York values", but both Trump and Clinton are steeped in the New York political economy, where one builds a fortune through political connections rather than entrepreneurial vigor. Want to build a new parking lot next to your casino or start up a new energy firm -- you don't bother with private investors or arms length transactions, you go to the government.
With that in mind, I particularly liked Don Buudreaux's quote of the day:
First, we labor under a ubiquitous threat of being shackled by crony capitalists. [Adam] Smith wondered how internally stable a free market could be in the face of a tendency for its political infrastructure to decay into crony capitalism. (The phrase “crony capitalism” is not Smith’s. I use it to refer to various of Smith’s targets: mercantilists who lobby for tariffs and other trade barriers, monopolists who pay kings for a license to be free from competition altogether, and so on.) Partnerships between big business and big government lead to big subsidies, monopolistic licensing practices, and tariffs. These ways of compromising freedom have been and always will be touted as protecting the middle class, but their true purpose is (and almost always will be) to transfer wealth and power from ordinary citizens to well-connected elites
