MINNEAPOLIS (AP) - As Republicans tighten their hold on Greater Minnesota and Democrats solidify their base in the state's urban areas, it's suburbanites who occupy both the physical and political in-between-land.
In statewide and Congressional contests, and in the race to control the Minnesota House, the Twin Cities suburbs are a big focal point of both parties' campaign efforts.
The Twin Cities suburbs - Anoka, Carver, Dakota, Hennepin, Ramsey, Scott and Washington counties, not including Minneapolis or St. Paul - represent a pretty small slice of the state in terms of landmass. So why do they get all the political attention?
They may not have skyscrapers like Minneapolis and St. Paul, but taken as a whole, the number of voters in the suburbs dwarfs the number of voters in the Twin Cities themselves.

How much bigger?
In 2016, there were nearly four times as many votes for president in the Twin Cities suburbs as in Minneapolis and St. Paul. In fact, there were nearly as many votes in the Twin Cities' suburban counties as there were in all 80 counties outside the Twin Cities metro.
Put together, the Twin Cities' 10 biggest suburbs alone account for 13 percent of the vote statewide. Compare that with about 7 percent of the statewide vote in Minneapolis and 5 percent in St. Paul.
It's not just the number of voters in the suburbs that makes them a focus for this year's elections.
It's also their penchant for voting for Republican candidates sometimes, and Democratic-Farmer-Labor candidates others - often on the same ballot. In a state where the cities are increasingly blue and Greater Minnesota is turning redder, many suburbs are still up for grabs for either party.
Look no further than the 12 districts - all of them suburban - that went for Hillary Clinton that also elected Republican state representatives on election night in 2016. Many of them are places that, in 2012, voted for Mitt Romney, but in 2016 switched over to Democrat Hillary Clinton.
District 49A, represented by Republican Dario Anselmo, exemplifies the phenomenon. Residents of this Edina district preferred Hillary Clinton by a 27 point margin, but sent Anselmo to the statehouse on a margin of 2 points.
That night, Anselmo took control of the district from Ron Erhardt, a longtime DFL (formerly Republican) incumbent.
In 2018, Democrats hope their candidate, Heather Edelson, can bring the seat back under DFL control as inner-ring suburbs like Edina turn bluer. As of the last campaign finance deadline, Republicans had barely spent any money in a district Democrats are targeting, a possible sign the GOP has written the seat off.
Seats that went for Clinton but elected Republicans to the House are on the DFL's list of top legislative targets. Democrats need a net gain of 11 seats to take back control of the Minnesota House.
Two of Minnesota's most closely-watched Congressional contests - the race between Jason Lewis and Angie Craig in CD2, and the race between Erik Paulsen and Dean Phillips in CD3 - are also largely suburban districts.
Not all suburbs are equally up-for-grabs for either party. In Andover and other further-ring suburbs, Republicans have held onto healthy margins. Brooklyn Park, a diverse suburb northwest of Minneapolis, votes more like the cities.
This November, it'll be places like Plymouth - a mid-sized second-ring suburb west of the cities - that are bellwethers for which way things are going, both in terms of statewide elections and when it comes to legislative control.
On the surface, Plymouth looks like many other second-ring Twin Cities suburbs: incomes are higher than places like Brooklyn Park and Hopkins, but lower than places like Lakeville. Plymouth's population is slightly more diverse than the state's as a whole.
But politically, it's a bit more complicated than some of its neighbors. In 2016, Plymouth re-elected incumbent Rep. Sarah Anderson, a Republican, but also voted for Hillary Clinton.
And that in a city with about 44,000 votes for president - more than Greater Minnesota's Kittson, Roseau, Lake of the Woods, Beltrami, Cook and Clearwater counties combined.
That far exceeds the number of votes needed to decide a statewide election, some of which, in recent years, have come down to just a few hundred or a few thousand ballots.
It's not just Plymouth that politicos are watching closely as elections near. Places like Maple Grove, Woodbury, Burnsville, Apple Valley and Edina are similarly large reservoirs of potential suburban swing: places where, with the right candidates in the right year, it could be either party's game.
