When Kansans vote Tuesday they will deal with different districts, a new requirement to provide photo identification and the smoke from Republican Party warfare.
Officials are predicting a low turnout at the polls, which will be open from 7 a.m. to 7 p.m.
In the Republican Party primary, Gov. Sam Brownback, the Kansas Chamber of Commerce, the billionaire Koch brothers, and Kansans for Life have been working to defeat a group of Republican senators who they say have been obstacles to their agenda.
Brownback said he got involved "because of the alliance in the state Senate between Democrats and some Republicans that join together to promote a Democrat agenda."
House Minority Leader Paul Davis of Lawrence said when he read that statement from Brownback he thought it was peculiar. "Do the people of Kansas want their representatives to work with each other or not? I believe the answer is a clear yes."
Meanwhile, those Republican incumbents were battling back with the support of teachers, bi-partisan union PACs and gaming interests.
"The moderates have really fought back in a more aggressive fashion than I think some of us who have been watching Kansas politics had anticipated," said Burdett Loomis, a political science professor at Kansas University.
"The moderates aren't going down without a fight," said Washburn University political science professor Bob Beatty. "It's a true battle. It's not like the U.S. men playing Nigeria in basketball."
While GOP state legislative races have dominated politics in much of Kansas, Douglas County is part of a Democratic primary for the 2nd Congressional District.
Lawrence and Douglas County had been split the previous 10 years between the 2nd and 3rd Districts, but redistricting brought the county entirely into the 2nd.
Scott Barnhart, Robert Eye and Tobias Schlingensiepen are vying for the Democratic nomination to face U.S. Rep. Lynn Jenkins, R-Topeka, who is seeking her third two-year term.
Barnhart is a farmer from Ottawa; Eye, an attorney from Lawrence; and Schlingensiepen, a pastor from Topeka.
Eye and Schlingensiepen have had the most active campaigns.
Back on the legislative side, two Republicans are vying for their party's nod in the 3rd Senate District. James C. "J.C." Tellefson, a former Leavenworth County commissioner, faces Anthony Brown, a state representative from Eudora. The winner will go against incumbent state Sen. Tom Holland, D-Baldwin City, in the November general election.
The newly drawn 3rd Senate District covers parts of Leavenworth and Douglas counties, including Basehor, Tonganoxie, Eudora, Baldwin City and about one-third of Lawrence’s population.
In the GOP primary in Senate District 19, two newcomers face off: Matthew Windheuser of Lawrence and Casey Moore of Topeka. The winner will face state Sen. Anthony Hensley, D-Topeka, in the district that covers western Douglas County, east Topeka and all of Osage County.
In Senate District 2, Ronald Ellis of Meriden faces Jeremy Pierce of Lawrence, but Pierce ended his campaign and threw his support behind Ellis, who is expected to challenge state Sen. Marci Francisco, D-Lawrence.
Lawrence state Reps. Barbara Ballard and Paul Davis, both Democrats, and Tom Sloan, a Republican, face no primary opponents.
Republican primaries are being held in two House districts that include portions of Douglas County.
State Rep. Connie O'Brien, of Tonganoxie, faces Sandra Bohne of Leavenworth in the 42nd House District; and Debra "Debbi" Childers of Auburn, Ken Corbet of Topeka, and Dana Webber of Scranton are running in the 54th House District. The winner in that race will face state Rep. Ann Mah, D-Topeka.
The newly aligned districts were ordered by a panel of three federal judges in June, producing massive changes in voters' political representation. The primary also will be the first statewide test of the Kansas law that requires photo ID to vote.
Critics of the law say it will suppress voting rights and cause confusion. Kansas Secretary of State Kris Kobach, a national proponent of voter ID laws, predicted it won't cause any problems.
