IOWA CITY, Iowa (AP) — A slim lead held by a Republican candidate for an open congressional seat in Iowa has gotten even smaller as counties recount their votes. Republican Mariannette Miller-Meeks led Democrat Rita Hart by 47 votes in the race for Iowa’s 2nd Congressional District in unofficial results before recounts began last week.

The Iowa Secretary of State’s office says Miller-Meeks’ lead has shrunk to 36 votes out of more than 394,000 cast as the recount continues. So far, 15 of 24 counties have completed recounts and sent their new unofficial totals to the state. None of the four counties Hart carried have reported new totals, including Scott and Johnson.
