MILWAUKEE (AP) - Before U.S. Rep. Reid Ribble was elected to Congress, he envisioned Democrats and Republicans gathering together to debate important issues and develop legislation. He was stunned when he arrived in Washington to find that members of the two parties often don't come together until it's time to mark up bills, and by then, they already feel antagonistic. Rep. Mark Pocan said he received a lesson in partisanship soon after his election to Congress in 2012.
