State legislator retirements are typically a problem for the party out of power. Members of the majority can chair committees, drive the agenda, and get plenty of attention from lobbyists. Life in the minority caucus is much less satisfying.

Although Iowa House Republicans enjoy a 59-41 majority, four GOP representatives have already confirmed plans to step down this year, with more retirements likely before the March 16 filing deadline. When incumbents don’t seek re-election, party leaders sometimes must spend more resources defending open seats, leaving less money available for top and especially second-tier targets.
