LEXINGTON —? Democratic Gov. Andy Beshear joined teachers union president Randi Weingarten Tuesday to rally opponents of a constitutional amendment that they warned would defund Kentucky’s public schools.

Beshear took issue with what he called “misinformation” being spread by supporters of Amendment 2. “You don’t have to read very far to know that those trying to get you to vote ‘yes’ on Amendment 2 aren’t telling you the truth,” Beshear said — a criticism later disputed by Jim Waters of the conservative Bluegrass Institute for Public Policy Solutions, which supports the amendment.

If voters approve the measure’s changes to the state Constitution, Kentucky’s legislature would for the first time be free to put public money into private schools. Kentucky is one of three states with similar questions on the ballot this fall.

Weingarten, president of the 1.8 million-member AFT which represents teachers, nurses and other professions, stopped for a news conference at Consolidated Baptist Church as part of a pre-election bus tour through multiple states where AFT is supporting political allies including the Democratic presidential ticket.

Weingarten, an attorney and former history teacher, praised the protections for public schools in Kentucky’s Constitution. “I’m here to say to Kentucky, if we want to have that Kentucky culture of public schooling being the equalizer for all? kids, we need to vote ‘no’ on Amendment 2.”

She said that in states that have funded vouchers to help pay private school tuition, most of the parents using them were already sending their kids to private schools. “And, in fact, many private schools in the country have raised their tuition.”

Thirteen states and the District of Columbia fund some? form of vouchers that provide a set amount of money for private? school tuition, according to the Education Commission of the? States. Thirty-three states, the District of Columbia and Puerto Rico have some form of “school choice” program, according to EdChoice, a nonprofit that advocates for the programs.

Josh Cowen, a professor of education policy at Michigan State University, told the gathering that voucher programs are failing students. He said 20 years of research led him to “call vouchers the education equivalent of predatory lending” because kids who leave public schools to attend the non-elite private schools that will accept them suffer declines in academic performance.

Cowen, formerly a professor at the University of Kentucky, is the author of “The Privateers: How Billionaires Created a Culture War and Sold School Vouchers” published recently by Harvard Education Press.

“When it comes to vouchers, it isn’t the school choice at all. It’s the school’s choice. The schools are doing the choosing,” Cowan said, adding that “30% of kids who do come to a voucher school from a public school end up leaving within the first couple of years … because they’re pushed out, asked to leave or they just can’t make it work.”

The movement toward school vouchers has been fueled by a network of super wealthy individuals and their nonprofit advocacy groups, most prominently Americans for Prosperity linked to Charles and David Koch. Another champion of school choice, Jeff Yass, a billionaire options? trader who lives near Philadelphia, has also put millions into a political action committee associated with Republican Kentucky U.S. Sen. Rand Paul, who is featured in television ads supporting Amendment? 2.

Saying he wanted to address “three pieces of misinformation,” Beshear ?said a pro-Amendment 2 flier had implied that he supported the measure because it would give him more options. “Let me be clear, I’m fully opposed to Amendment 2.”

Beshear also disputed assertions in advertising for Amendment 2 that its passage would raise teachers’ pay, saying “that? fails math.” Beshear also said that even though supporters ?argue that Amendment 2 in itself makes no policy changes, Republican lawmakers through their past votes for charter schools and a tax credit to support private schools have made their intentions clear, even as their commitment to further cuts in the state income tax will reduce revenue available for education.

“Amendment 2 would allow Frankfort politicians to take taxpayer money away from public schools and send it to unaccountable? private schools,” Besher said. “Let me tell you the people of Kentucky do not want that and when they are educated on what this amendment will actually do, they will vote against it as many? times as you’ll let them.”

Waters? of the Bluegrass Institute disputed Beshear’s assertion that Amendment 2 supporters are spreading misinformation.

“Voters are not voting on vouchers or any type of policy. The amendment removes barriers so legislators can create school choice policies without being struck down by the courts.”

Waters also said data show that teacher pay is “positively affected by choice policy.” The Bluegrass Institute in August published a brief by John Garren, a University of Kentucky emeritus professor of? economics, that found “increased school choice raises the demand for teachers’ services” and that “this increased? demand pushes up pay for teachers generally in public, private, and charter schools.”
