Wisconsin Superintendent of Public Instruction Tony Evers is a cheater.

That’s the charge from Gov. Scott Walker, who is facing off against Evers in a very close race for re-election. And there’s plenty of evidence to back it up.

Documents Evers submitted as part of his official state budget for the Wisconsin Department of Public Instruction show he plagiarized large portions of the document from at least three sources, lifting paragraphs virtually verbatim, Politico reports.

“The largest example of text taken from another source without attribution examines summer learning loss. Fifteen paragraphs of Evers’ document is nearly identical to a 2016 blog post written by an intern for the Thomas B. Fordham Institute, a conservative education think tank based in Washington, D.C.,” according to the site.

Another section of the document appeared very similar to a post from the National Collaborative on Workforce and Disability, while yet another was cut and pasted directly from Wikipedia.

Walker’s campaign discovered the plagiarism after running Evers’ proposed education budgets through special software. The campaign released its findings on Friday, shortly before the first gubernatorial debate. Walker’s campaign released three other examples of intellectual theft over the weekend.

“According to documents released on Sunday, the GOP has found at least three other instances where Evers submitted plagiarized work,” The Daily Caller reports. “In one glaring example, the Democrat’s budget proposal contained a four-paragraph section that was nearly verbatim to a national policy group – the only difference was that Evers’ submission changed the word ‘students’ to ‘pupils.’ Additionally, Evers’ most recent budget proposal included a passage that (was) taken verbatim from previous work and was not properly cited.”

“Tony Evers has staked his entire campaign on ‘what’s best for our kids’ but when it comes to the most important action he takes in his current job – preparing an education budget – he’s not only peddling empty promises but also stolen ideas,” Walker spokesman Brian Reisinger said.

“An education would know the consequences of plagiarism, and this is damning proof that he’s a Madison bureaucrat who will always take the easy way out instead of providing the kind of leadership needed to stand up for hard-working families,” he said.

The most recent Marquette University Law School poll, conducted in early October, shows the Wisconsin governor’s race as a virtual tie with two weeks to go before Election Day. A Real Clear Politics average of all polls since August 18 puts Evers up 3.6 percentage points among likely voters.

“So far, Tony Evers has said it’s not a big deal (is that his message to a student who plagiarizes?), it was a one-time thing (it happened over and over) and that I adopted his budget (he submitted it hoping I would),” Walker posted to Twitter on Sunday.

“Tony Evers’ TV ads are attacking me on education yet his latest defense for the blatant plagiarism in his past and present budget documents is that I adopted his budget request. Which he asked me to do and called a ‘pro-kid budget,’” Walker wrote. “Tony Evers’ hypocrisy is amazing – even for a Madison politician.”

Evers, meanwhile, is attempting to downplay the plagiarism, though his campaign did confirm it happened.

Thomas McCarthy told Politico the repeated omission of proper attribution was “an oversight by staff when drafting the paper.”

“(Walker) is grasping at straws because he can’t defend is record of cutting $800 million from Wisconsin’s public schools, undermining protections for people with pre-existing conditions and always putting his special interest backers first,” Evers aide Sam Lau said in a statement. “That’s what’s important to voters.”

Other local political “experts” shared a similar perspective.

“The plagiarism charge will disrupt the Evers campaign but it is not likely to have much impact on how voters view the candidates,” Barry Burden, director of the Election Research Center at the University of Wisconsin-Madison, told Politico.

“Four years ago there was a similar charge about Walker’s opponent plagiarizing part of an economic plan,” he said.

The 2014 plagiarism allegations were the beginning of the end for Mary Burke, who ultimately lost the election to Walker by a little over 100,000 votes.
