MADISON, Wis. (AP) _ Wisconsin Gov. Scott Walker is headed to Virginia to campaign for Republican gubernatorial candidate Ken Cuccinelli in the waning days of the campaign.

Walker's campaign spokesman Jonathan Wetzel said Wednesday he is scheduled to be with Cuccinelli on Saturday, just three days before the election. Cuccinelli faces Democrat Terry McAuliffe in the hotly contested race.

Most polls have showed McAuliffe with a comfortable lead over Cuccinelli.

Walker is popular among conservatives after he became the first governor in U.S. history to survive a recall election. The recall last year was spurred by anger over his 2011 proposal that effectively ended collective bargaining for public workers.

Walker is releasing a book next month about that union fight and recall, fueling speculation that he will run for president in 2016.
