Ratings Changes: After Arizona Special Election, an Expanding House Battleground

April 26, 2018

On the heels of Tuesday's narrow Republican win in Arizona's 8th district, we have an updated outlook and some ratings changes from the forecasters at Sabato's Crystal Ball. Ratings changes were made to 15 districts, including 10 new races that moved from safe to likely Republican.

In their own words:

"Overall, our House outlook remains the same: Democrats are about 50-50 to win the House. What these ratings change do is make clear that in the event of a big wave, there are some districts that might not seem competitive on paper that could flip, particularly because a deep bench of Democratic candidates is in place to capitalize on a potentially great environment in the fall. That’s where one could see Democrats picking up substantially more than the 23 net seats they need to win House control. However, the Democratic wave could fail to materialize, and Democratic gains could be limited to the teens. At this juncture, the range of possibilities in the House is wide. We realize that may be an unsatisfying and overly cautious assessment, but that’s where we’re at right now with the election still half a year away."

As most of the shifts were from safe to likely Republican, the overall forecast changes little, although the map isn't quite as dark red as it was. Republicans are favored in 211 seats, Democrats 198, with 26 toss-ups.
