In both states, Christie is still polling in the single digits and remains around seventh in the crowded GOP field, according to the new NBC News/Wall Street Journal/Marist College polls. The polls were taken after the second debate.

Christie has recently started to campaign more aggressively in Iowa. The governor saw his numbers jump in Iowa from 2 to 4 percent support. In New Hampshire, Christie received 7 percent, a 2 percent increase.

Donald Trump remains the clear front-runner, but he is seeing his numbers drop. In both states, Trump dropped from 28 to 21 percent. Despite the decrease, he still has almost 25 percent of the likely Republican voters who say they will support him.

Like Trump, retired neurosurgeon Ben Carson, has also slipped in the polls, but remains in second place in Iowa.

Carly Fiorina, who many political pundits declared the winner of the Sept. 16 debate, saw increases. She's now in second place in Iowa with 16 percent support.
