The left-wing comedian Jon Stewart is at it again after ripping conservative Republicans for going after public sector collective bargaining. Stewart updated the situation in Wisconsin Thursday night on the “Daily Show,” reporting on Wisconsin Gov. Scott Walker introducing his new budget proposals. “He has put public sector unions on notice, and particularly teachers, that the gravy train is over – even if the gravy is actually lunchroom cafeteria-grade gravy-like rehydrated soy chips,” Stewart spun, painting the comfortable pensions and benefits of Wisconsin public school teachers as dog food compared with infamous Wall Street bonuses. He also shifted the debate – instead of going after public sector unions, conservatives somehow are anti-teacher, according to Stewart's logic.
