Mayor Rahm Emanuel on Wednesday accused Gov. Bruce Rauner of “governing through anger” and predicted that Republicans and Democrats alike would chose “loyalty to kids over loyalty to the governor” by overriding Rauner’s veto of a school funding bill.

One day after Rauner followed through on his threat to veto the bill, Emanuel accused his old friend of blowing a “historic opportunity” to rewrite a formula that “fundamentally harms poor kids and kids of color.”

“Re-writing the school formula was a product of the governor’s commission, which is why the governor agrees with 90 percent of it. You can’t then just want to veto it because of a pique of anger,” the mayor told reporters.

“He is governing through anger.”

Emanuel said Rauner has already been overridden four times because “people of both parties in the legislature have decided to go independent, around the governor to start moving Illinois forward.”

That is precisely what the mayor believes will happen this time.

“He’s chosen to play politics. He’s chosen to play divisiveness rather than progress….Like on the budget, like on…fiscal issues like pensions, Democrats and Republicans will go around the governor just like in Washington they’re now going around the president,” the mayor said.

Emanuel noted that 250 school districts that serve poor kids around the state “do much better” under the new formula. They, too, will lobby for an override because the governor’s veto has “harmed them,” the mayor said.

No matter what happens, Emanuel made one thing perfectly clear: Chicago Public School schools will open on time and remain open for, what the mayor calls a “full school day and a full school year.”

Once again, the mayor refused to say how he would do that or what taxes he might raise in the event that an override of the governor’s veto fails.

Rauner’s spokesperson Laurel Patrick called the mayor’s broadside “disappointing.” She argued that Rauner is “committed to helping Chicago – but not at the expense of every other student in Illinois.”

Patrick argued that the governor’s amendatory veto would give Chicago Public Schools “millions” more than it would receive under the existing school funding formula.
