NY Times on Scott Walker

One of the possible Republican candidates for the Oval Office is Scott Walker.  For those unfamiliar with him, he basically is a union busting governor.  The NY Times states:

More than any of his potential rivals for the White House, Mr. Walker, 47, is a product of a loose network of conservative donors, think tanks and talk radio hosts who have spent years preparing the road for a politician who could successfully present their arguments for small government to a broader constituency.
Mr. Walker has embraced those goals in Wisconsin, and the promise of his fledgling presidential campaign is to do the same in Washington. The little-known governor-elect honored in Milwaukee has become something of a conservative hero, backed by wealthy donors like Charles G. and David H. Koch and revered as a leader brave enough to face down unions and their liberal supporters.

Although crowded, the next president could either significantly help or hurt unions.  Especially targeted are teacher unions.
