The 2006 Wisconsin gubernatorial election was held on November 7, 2006. Incumbent Democratic Governor Jim Doyle ran for re-election to a second term in office. Doyle was unopposed in the Democratic primary, and he faced U.S. Representative Mark Green, who was unopposed in the Republican primary, in the general election. The campaign between Doyle and Green was competitive and hotly contested, but Doyle, whose approval ratings hovered around 50%, had the upper hand. In the end, Doyle defeated Green by a fairly comfortable margin, improving on his 2002 victory in the process.
