A lot of people still think he has no chance at the nomination. Their hypothesis is that the Republican field is still very wide, so Trump is capturing the largest piece of the pie, but once other candidates start dropping out, they won't fall to him, but rather concentrate on another candidate. I tend to believe this has merit since you can position yourself a certain way and gain a lot of popularity with certain segments of the Republican party/conservatives, but distance yourself from the rest of the party. The fact that this group has largely identified itself as the Tea Party and has been around for several election cycles and Mitt Romney, the most moderate of the of 2012 candidates ran away with the nomination in 2012, speaks well to this hypothesis.
