U.S. Senator Charles Grassley weighed in on the Iowa Supreme Court’s decision to allow former Congresswoman Abby Finkenauer to remain on the primary election ballot during his visit to Atlas Molded Products in Washington Friday.

The court ruled Friday that the Democratic candidate qualifies to be on the ballot, overruling a lower court decision that ruled her not eligible after two Republicans challenged her petition papers, saying signatures from at least two counties did not have the required date accompanying them. When asked, Senator Grassley said he accepted the Supreme Court’s unanimous decision, “A couple people in the state thought she didn’t and so the process that he’s referring to is what she went through and she ended up satisfying the government, but I had 42 counties with more than 100 signatures. So there’s a lesson to learn for everybody, don’t count on just getting the minimum number of signatures.”

Finkenauer now faces off against Michael Franken and Glenn Hurst for the Democratic nomination in the June 7th primary, while Grassley faces opponent Jim Carlin for the Republican nomination. The supreme court’s reasoning in affirming Finkenauer stemmed from changes the state legislature made to election laws last year that identified specific circumstances when objections to petitions should be sustained. The law did not include missing or incorrect dates as one of the grounds for sustaining an objection to a petition. Grassley told KCII he won’t tell the legislature what they ought to do regarding whether they should pass a law to address that omission.
