In December 2013, Chris Christie dominated the field in the just-forming race for the 2016 Republican presidential nomination. With a rating of 20 percent in the RealClearPolitics average of polls, the New Jersey governor was well ahead of Jeb Bush, Scott Walker, Marco Rubio, Rand Paul, Ted Cruz — everybody.

Now, Christie sits at 4.8 percent in the average, a bit better than Rick Perry, Rick Santorum and Bobby Jindal, but behind all the other candidates he once led.
