RealClearPolitics has polling averages for the nation's gubernatorial races. Accessed Monday, their map shows 23 Republican governors leading, 19 Democrat governors leading, and eight toss-ups.
This remains consistent with the numbers reported by RCP last week and the week before. Last week, the gubernatorial races in Alaska and Arizona became safer for the Republicans.
Regarding Oregon's gubernatorial race, opb.org reported last week that Democrat incumbent Kate Brown held what it called a "tenuous lead" over Republican challenger Knute Buehler.
Brown had the support of 40 percent of voters while Buehler had 35 percent, the data being taken from a survey of 500 Oregonians with a margin of error of 4.4 percentage points.
