Presidential races are always close and early polls like this do not tell much. Most people have never heard of Romney yet.
It is always fun to watch jaywalking on Jay Leno. There, Jay shows pictures of famous people (e.g. presidential candidates) to passersby who try to guess who it is in the picture. The results are quite depressing. They hardly know who is the sitting president but beyond that absolutely nothing. These people vote.
There is one consistent trend in the average of all of the polling data:
In all of the early primary states, Romney has been trending *UPWARD*.
Even on the national scene, where Romney is still just behind McCain, Romney’s numbers are trending upward.
