Republicans have a great chance to expand their stranglehold on governor's mansions this year, with 11 states holding governor's races.

Eight of those seats are held by Democrats, including all of the at-risk states, according to The Fix's handy new interactive map of the governor's races.

According to The Fix's current ratings, one Democratic-held seat (North Carolina) leans toward the GOP, while three (Montana, New Hampshire and Washington) are toss-ups. All four states are open seats with retiring Democratic governors.

Two more seats (Missouri and West Virginia) lean toward Democrats but are potentially competitive.

Meanwhile, all three GOP-held seats up this year — Indiana, North Dakota and Utah — are rated as solidly Republican.

In other words: Democrats have their work cut out for them. It's a very tough map.

Republicans already control 29 of the 50 governorships, and they've got at least a decent chance to win in four states. Which suggests — if all goes just about perfectly — that the GOP could control two-thirds of these seats come January.
