If Romney pulls off a victory of that magnitude, he could be on a glide path to the nomination. But there are warning signs for the Republican Party that the primary has taken a toll on Romney and the rest of the GOP field.

And, Romney runs even or leads Gingrich in the traditionally more conservative northern part of the state. In addition, more GOP primary voters said Romney represented their views on immigration than any other candidate.

Romney also leads among evangelical Christians, receiving the support of 34 percent, compared to 28 percent for Gingrich. Six-in-10 GOP primary voters said they believed Mormons are Christians.

More voters also said they saw Santorum as the candidate who best represents the middle class.
