Three Senate races shift toward Democrats in Cook ratings

The Cook Political Report shifted its rating of three Senate races toward the left Tuesday, upgrading the chances that Democrats will win control of the Republican-held chamber in November.

Cook shifted Kansas from “Lean Republican” to “Toss Up,” New Hampshire from “Toss Up” to “Lean Democrat” and North Carolina from “Lean Democrat” to “Likely Democrat.” Those changes help move the number of possible pickups for Democrats from two to six seats, according to Cook, a nonpartisan election handicapper.
