States with largest percentage of uncontested state legislative races?

Arkansas is ranked second nationally in terms of uncontested legislative seats this year, which I think can be attributed directly to term limits. 80.5% of our legislative seats have already been determined. Massachusetts is first with 84% of its legislative seats having no contested election. Contrast that with Minnesota, where 99.3% of the legislative seats are contested.

Few legislative chambers could change
While the Arkansas and federal legislative chambers will be Democratically-controlled after Tuesday, there are a few chambers around the country that are in play:

• Alaska Senate: It's currently 9D/11R, and there are a few competitive races.
• Ohio House: Currently 46D/53R, and the Democrats are outspending the Republican counterparts in the legislative races. With it being a battleground, just about every candidate has stumped alongside the presidential ticket in the state.
• North Dakota Senate: Currently 21D/26R, and three of the four open seats are Republican-held.

Here's a map showing the current control of state legislative chambers:

Red: Both chambers controlled by Republicans
Blue: Both controlled by Democrats
Purple: One party controls one chamber and the other party controls the other
Nebraska has a unicameral, non-partisan legislature
