There is nobody among the contenders for the White House, from both parties and including Christie, up to the task of getting this nation out of trouble.
In the case of Christie, he has no economic policy per-se (other that cutting taxes for the upper class which is not an economic policy but an ideological stand) and he does not seem to have a grasp of foreign affairs which creates the danger that the neo-conservatives will control foreign policy in his administration, with wars everywhere: Guns instead of butter.
Talk and speeches are insufficient to solve problems. As I believe president Lincoln said once: “You can fool all the people for some time, some people all the time, but you can not fool all people all the time ” or something like that.
I am really hoping that someone else comes up.
