Scott Walker’s supporters and critics agree on this much: The governor has delivered on his campaign promise to speed up and simplify permits for environmentally sensitive activities like mining and digging high-capacity wells.

“I will make sure the DNR treats Wisconsinites as customers, not criminals,” then-candidate Walker said in 2010, saying the state Department of Natural Resources was “out of control.”

Despite their differences, Mary Burke and Gov. Scott Walker have some common ground. Both talk about keeping taxes low, creating jobs and maintaining the Act 10 benefits changes for public employees.

But perhaps no issue demonstrates such a stark division between the two gubernatorial candidates more than education — a split that appeared in high relief last week when Walker called on the Legislature to repeal the Common Core State Standards.

The governor’s race has been dominated so far by pocketbook topics like jobs and taxes, but social issues — including same-sex marriage and abortion rights — have started spilling into the debate.

Gov. Scott Walker began the year warning his fellow Republicans across the country to avoid “taking the bait” on divisive social issues, arguing that the GOP should instead focus on the economy.

A Republican governor, Tommy Thompson, started Wisconsin’s BadgerCare health insurance for low-income families in 1999.

A Democratic governor, Jim Doyle, expanded the program in 2008.

Democratic gubernatorial candidate Mary Burke wants to repeal major parts of the divisive 2011 law known as Act 10, including several provisions that crippled the political power of public-sector unions.

In her most detailed comments yet on the subject, Burke also made it clear that she would keep or modify other parts of the law, including a requirement that state employees pay at least 12 percent of their health insurance premiums and a ban on public employers picking up the employee share of pension contributions.

While cutting taxes three times in less than a year, Gov. Scott Walker floated a radical and controversial idea for Wisconsin — eliminate the state income tax.

“That’s one thing for us to look at,” Walker told WisPolitics in December. “Is that feasible? What would that mean in terms of an economic boost?”

Even many of Gov. Scott Walker’s supporters acknowledge he won’t meet his pledge to help create 250,000 jobs in Wisconsin by the end of his first term.

Whether voters hold that against him in November when they go to the polls to decide on giving the first-term Republican governor another four years in office will be one of the key questions of the election.
