Carrie Dann writes: It's been a recurrent theme throughout the last days of this midterm election cycle: "New poll shows [Insert Senate race that didn't seem competitive three weeks ago] is tightening."
According to some polls, candidates in a handful of states have made apparent gains after months of trailing. In Pennsylvania, two new surveys show Democratic Rep. Joe Sestak – who has struggled to stay within striking distance of Republican Pat Toomey since the state's May primary – now polling within the margin of error. A St. Norbert College/Wisconsin Public Radio poll released Tuesday put Democrat Russ Feingold just two points behind GOP nominee Ron Johnson. In the pricey (and contentious) California Senate contest, a new PPIC poll shows GOP candidate Carly Fiorina catching up with incumbent Barbara Boxer. Gaps have also seemingly closed in Colorado and Alaska.
