MADISON, Wis. (AP) _ Republican New Jersey Gov. Chris Christie is singing the praises of Wisconsin Gov. Scott Walker in Time magazine's list of the 100 most influential people of 2014. Both Christie and Walker are considering 2016 presidential runs, making Christie's endorsement of Walker all the more interesting. But it's also not unprecedented. Christie is chairman of the Republican Governors Association and has previously spoken highly of Walker as he faces re-election this fall. Christie's three paragraph item on Walker cites his fight over collective bargaining and his successful defeat of a recall election in 2012 as signs of Walker's leadership. Walker is pictured leaning against a Harley-Davidson motorcycle with the state Capitol in the background. In 2011, Walker wrote a piece for U.S. Rep. Paul Ryan when he made the list.
