Laura Belin and Spencer Dirks discuss the top Iowa political stories from the week, starting with reaction to President Joe Biden's decision to stand down as the Democratic nominee and the possible impact on down-ballot races. Other topics discussed: Attorney General Brenna Bird's prime-time speech at the Republican National Convention, how a rift with team Trump could affect Senator Joni Ernst's future prospects, strong Democratic fundraising in two Iowa Congressional races, and the legal state of play surrounding Iowa's near-total abortion ban and a proposed carbon pipeline.
