Scott Walker

Governor of Wisconsin (2011–2019) — who passed Act 10 (eliminating most public sector collective bargaining rights), survived a recall election, and was briefly a leading 2016 Republican presidential candidate before dropping out early.

Creates the Wisconsin model for confronting public sector unions — Walker's Act 10 was the most aggressive state-level challenge to public sector union power in American history, survived a Supreme Court challenge and a recall election, and saved Wisconsin $5B in pension and benefit costs.
