Leftists in Wisconsin vandalized a public school ahead of a visit by Republican Governor Scott Walker, who enacted reforms to place students ahead of the powerful teachers unions.

Custodial staff at Messmer Preparatory school were replacing locks Friday morning after the previous ones had been filled with metal and glue overnight, said the school’s Development Director Jeffrey Robb.

“We’re very disappointed,” he said.

The vandalism came hours before Gov. Scott Walker was scheduled to visit the school to read to second- and third-graders. Walker plans to read, “Oh! The Places You’ll Go,” by Dr. Seuss.

Even after issuing an obligatory denial of involvement, the Milwaukee chair of the Students for a Democratic Society said, “We’re not going to let him go anywhere, especially in our community, without him being protested.”

Leftists are still pissed at Walker for reforming public sector union laws. He decided to place the interests of students over those of union bosses — who heavily support far-left causes — and that has them pissed to crap.

So they’ve tried to destroy a conservative Supreme Court justice. And they failed. Then they tried to get that justice charged criminally. And they failed. Then they tried recall elections. And they failed.

Now they’re resorting to vandalizing schools.

But remember, it’s all about the students for these people. All about the low and medium-income children who are our future. Up to the point when those children get in the way of their sweet pensions and political power. Then it’s time to vandalize schools.
