Former Indiana Governor Mitch Daniels says Illinois Governor-elect Bruce Rauner faces steep challenges, but has a chance to enact real change.  Rauner says he wants to emulate Daniels during his stint as chief executive, which begins today.  Both are Republicans and successful businessmen.  Like Rauner, Daniels inherited a budget shortfall when he took office in 2004.  But he turned the deficit into a surplus, largely through spending cuts.  He also privatized the Indiana Toll Road and angered labor unions by using an executive order to strip state workers of their collective bargaining power.  Daniels said during an interview with The Associated Press that Rauner faces far worse budget problems, and must deal with a heavily Democratic Legislature.  But he says there are ways for Rauner to push through his agenda.
