Nate Cohn: “Republicans hold a narrow but broad advantage across this year’s governor’s contests, according to the newest round of data from The New York Times/CBS News/YouGov online panel of more than 100,000 respondents. They hold at least a nominal lead in 22 of this year’s 35 governor’s races.”
“The sizable Republican advantage is mainly a reflection of incumbency. The Republicans won 23 of 37 states in 2010, and all but three of those Republicans are running for re-election this year. The three retiring Republicans are all from red states.”
