Whoever wins the June 3 primary to represent Iowa’s third district, I think we all should agree that facing a primary challenge has nudged Congressman Leonard Boswell in some good directions. Not only has he come on board with federal legislation he didn’t back in the past (such as the Safe Climate Act), he has also stepped up his constituent service.

The Des Moines Register ran this article on Friday about Windsor Heights moving closer to getting a unique zip code for its residents:

Windsor Heights, which is surrounded completely by other cities, shares the ZIP codes of 50311, 50312 and 50322 with neighboring Des Moines and Urbandale.

Boswell in January introduced legislation, at the urging of Windsor Heights officials, that directs the postal service to designate a unique ZIP code for the city. Iowa Sens. Charles Grassley, a Republican, and Tom Harkin, a Democrat, introduced companion legislation in the U.S. Senate.

Windsor Heights spearheaded a crusade 10 years ago to secure a unique ZIP code for the community, where problems with mail deliveries have irritated residents for years.

Catch that? They’ve been working on this for 10 years. I know Windsor Heights residents who asked Boswell or his staffers years ago to help us get a zip code.

Windsor Heights officials get about 50 complaints a year about the city’s lack of a unique ZIP code. The issue is the top one residents complain about, city officials said.

[City administrator Marketa] Oliver praised the “dogged perseverance” of city leaders in getting the postal service to conduct the survey.

“When I heard, I went ‘Woo hoo,’ ” she said.

Mayor Jerry Sullivan contributed the announcement to support from the Iowa Congressional delegation.

“Leonard (Boswell), if he hadn’t spearheaded this for us, we wouldn’t have gotten to where we are today,” Sullivan said.

I don’t think it’s a coincidence that Boswell took the initiative on this issue right after Ed Fallon declared he was running for Congress.

This morning my family attended the annual pancake breakfast run by the Windsor Heights firefighters, and a person who has served on the city council agreed with me that we wouldn’t have made progress toward getting a zip code if it were not an election year.

I have no idea whether Windsor Heights’ three precincts will go for Boswell or Fallon on June 3, but I think all of the suburb’s residents should be glad the incumbent has been extra motivated to deliver to constituents lately.
