(CNN) - Last week, all systems were go for Kevin Weiland to challenge fellow South Dakota Rep. Stephanie Herseth Sandlin in the Democratic primary.
He put out a statement about his intentions and even launched a campaign Web site. But on Wednesday, Weilend decided to forgo a campaign to unseat the congresswoman.
It was the second time this month that Herseth Sandlin has avoided a primary challenger motivated, in part, by her opposition to President Obama's health care reform efforts.
Steve Hildebrand, a top campaign strategist for Obama, was the first person to threaten a challenge. He decided against it after the health care legislation was approved by Congress, and Hildebrand endorsed Weiland's challenge to Herseth Sandlin.
But Weiland said in a new joint statement with Herseth Sandlin that he has decided to endorse the congresswoman after receiving her word that she will not back the Republican call for repeal of the health care bill.
"After a great deal of thought and consideration, I have decided today not to run for Congress, both because of my concern for what the net effect would be on our political party retaining the seat in the next Congress, but also after receiving assurances from Stephanie that she will not vote to repeal the recently-passed health care reform law, however will work to make it better," Weiland, a doctor, wrote in a message posted on his Web site.
As for Herseth Sandlin, she noted that despite her opposition to the health care reform bill, it "does include a number of good provisions that I support." The congresswoman also said she would work with Weiland to improve health care in the state.
