Where They Stand: Scott Walker on issues of 2016 campaign

(AP) — Where two-term Wisconsin Gov. Scott Walker stands on various issues that will be debated in the Republican presidential campaign, a race he's joining.

[...] he's also questioned whether the current policy on legal immigration makes economic sense, suggesting he might side with those who believe high numbers of immigrants — legal or not — suppress wages.

Walker also opposes same-sex marriage, voting for a state constitutional amendment in 2006 that banned it.

Walker called the Supreme Court's decision legalizing gay marriage in all 50 states a "grave mistake."

Walker opposed the death penalty until 2006, when he switched positions, saying he believed that if DNA evidence proved the guilt of a person, the death penalty was justified.

Walker supports Wisconsin's first-in-the-nation school voucher program, under which taxpayers pay for students to attend private rather than public schools.

Walker proposed, just six weeks after taking office in 2011, that public employees except for police and firefighters pay more for pension and health care benefits, and only be allowed to bargain collectively over base wage increases no greater than inflation.

Walker this year also proposed eliminating tenure protections for University of Wisconsin faculty and staff from law as part of a broader proposal to make the university independent from state oversight and regulation.

Walker also joined more than a dozen other coal-reliant states suing the Environmental Protection Agency to block the so-called Clean Power Plan, which would require states to cut carbon dioxide emissions by 30 percent by 2030.
