Isn't ARG based in NH? IIRC, during the primaries, ARG's NH polls were notably less insane than their polls of other states. Maybe because they're local, they knew which polls to copy off of in order to get reasonable looking results (or, less likely, they actually know how to poll the New Hampshire primary). Doesn't necessarily hold up for the general election though.
They are, yet they still managed to butcher 2006 impressively. Not that hard to do with landslide races, but still...they're bad everywhere.
