Pollsters don't generally call cellphone-only voters. Are they getting the full picture? As more young people eschew landline phones for mobiles, there is a concern that the polls are skewing towards older, more traditional voters. (Strangely, to illustrate this point, the Globe highlights the cellphone-only demographic of a 35 year-old Republican operative who reveres Nixon.)

In any case, the proof will be in the pudding, and the Iowa polls were right on the money. Looking at this, who would you put your money on?

If you really want to avoid pollsters, set them on silent ring.
