GOP Improves Odds of Taking Senate

The Upshot: “With the addition of the YouGov estimates to our model, the overall outlook for the Senate remains roughly the same. The Republicans appear to have a slight advantage, with the most likely outcome being a Republican gain of six seats, the minimum they need to finish with a 51-49 seat majority. But we, like many other forecasters, would not be surprised by a gain of anywhere from four to eight seats.”

“Summing up the possible outcomes, our model gives the Republicans a 60 percent chance of taking control, up from 54 percent on April 1.”
