The battle for control of the U.S. Senate is getting closer ? much closer. Little more than a week ago, our Balance of Power summary showed the Republicans leading 50-45 with five states in the Toss-Up category.

….Today?s changes all involve Republican incumbents who have been struggling all year. In Montana, Senator Conrad Burns (R) has fallen behind Jon Tester (D). Rhode Island Senator Lincoln Chafee (R) survived his primary but starts the General Election as a decided underdog. Sherrod Brown (D) is enjoying a growing lead over Ohio Senator Mike DeWine (R).

They now rate the Senate race as almost dead even: 49 seats are Republican or Leans Republican while 48 seats are Democrat or Leans Democrat.
