Methodology
For each state, the map uses the average of all public telephone polls (internet polls are not included in the average) taken within 30 days of the most recent poll available in each state. For example, if the most recent poll in Ohio was taken on July 1, the average includes all polls conducted between June 1 and July 1. States within a three-point lead for the Republican or Democratic candidate are classified as toss-ups; states outside the three-point lead are allocated to the respective party. For states where primaries have yet to occur, the map uses polling match-ups between the candidates leading in polls among each party's primary voters.
Election 2010: State of the Race
The victories of Sen. Michael Bennet (D) and Ken Buck (R) in the Colorado Senate primaries moved the Centennial State from leaning Republican to a toss-up, but Pennsylvania and Ohio moved from toss-ups to leaning Republican to net one seat for Republicans over the past week. Democrats are still projected to hold 49 seats, while Republicans are at 45 seats, one seat leans independent, and five are still up for grabs.
