More than two weeks ago Chip Cravaack's campaign released an internal poll showing him 3 points behind Jim Oberstar, 45-42. This put not only the CD8 race on Republicans radar, but next door in CD7 they assumed Colin Peterson must be vulnerable too. In response to the increasing chatter about weather he was in a tight race or not Peterson's campaign released an internal poll of their own showing him wiping the floor with Lee Byberg 54-20.
Not only can we learn something from these two polls, but how the series of events unfolded is also of educational value.
