In politics, advance agreement by legislators to vote for one another's bills. Logrolling is most common when legislators are trying to secure votes for bills that will benefit their home districts. For example, a group of congressmen from the Middle West pushing for higher dairy prices and a group of southern congressmen supporting higher tobacco prices might make a logrolling agreement in order to get both bills passed.
