“By any measure … the result is that we’re not going to have enough revenue to meet our needs,” Gottlieb said. “Congestion and delay are going to increase. That is fact.

“If that’s your position, accept the consequences of that.”

Gottlieb previously criticized Walker in an interview with the Milwaukee Journal Sentinel, saying the governor has been “increasingly inaccurate” in describing funding for the state highway system.

Gottlieb said Tuesday he is not affiliated with Evers’ campaign but declined to say who he’s supporting in the election. He is not the first former Walker ally to speak out against him during this campaign: two other former Walker Cabinet secretaries have cut campaign videos for Evers criticizing the governor.

Walker firm on gas tax

Walker signaled Tuesday that if re-elected, he would maintain his opposition to a gas-tax increase not offset by a tax cut elsewhere.

“I’m making that same promise right now: I will never raise the gas tax without a corresponding or greater decrease in the overall tax burden,” Walker said.
