A week from Tuesday, voters will settle a bitter and nasty fight between two Republicans vying for the nomination to go up against Democratic incumbent Rep. Tim Walz this fall. "Unelectable” and “hypocritical" are among the insults Mike Parry and Allen Quist have thrown at each other as they compete in a GOP primary in Minnesota's 1st Congressional District, the Associated Press reports.

Allen Quist and Mike Parry plan to run in Minnesota's 1st Congressional District primary election in August. Neither candidate received enough votes after 23 ballots at the Republican endorsing convention to run against DFL Congressman Tim Walz.

A Republican primary fight between state Sen. Mike Parry and former state Rep. Allen Quist in southern Minnesota sharpened this week, with the candidates trading insults and charges of distortion. The two will square off in an Aug. 14 primary, and the winner will take on Rep. Tim Walz, D-Minn., in November.

Minnesota voters will set the stage for an array of political races when they cast their ballot on Tuesday. Secretary of State Mark Ritchie told the Red Wing Republican Eagle that primary turnout will be low, despite the closely watched primaries in the 1st and 8th Congressional Districts.

Allen Quist and Mike Parry are both seeking the GOP endorsement to run against Rep. Walz in November. Republicans will gather for their 1st District Convention in Mankato Saturday. Walz is seeking his fourth term in Washington.

In a letter to GOP activists Quist says he'll announce his challenge to Democrat Tim Walz on Thursday. Quist failed to gain the Republican endorsement in 2010. He was a candidate for governor twice in the 1990's.

After 23 rounds of voting, GOP delegates adjourned the 1st Congressional District endorsing convention without agreeing on a candidate to face U.S. Rep. Tim Walz this fall. Both Allen Quist and Mike Parry are seeking the GOP endorsement, but neither received the 60 percent of delegates needed for the endorsement. Republicans plan to try again at a second convention in the next few weeks.
