A new Quinnipiac poll shows Sen. Chris Dodd (D-CT) gaining ground against former Rep. Rob Simmons, the frontrunner for the Republican nomination for Senate next year. Dodd leads the other Republicans in head-to-head matchups. The Washington Post‘s Chris Cillizza has more. Although it could be seen as a sign that Dodd is down but not out, my sense is that these numbers are the sweet spot for the Connecticut GOP: Dodd is polling just well enough to deter a serious Democratic primary challenger but not well enough to beat Simmons. In fact, he barely beats and fails to break 42 percent of the vote against any of the lesser known Republican challengers. Linda McMahon was not included in the poll.
