"It’s easy to think of congressional redistricting as a once-in-a-decade event, but it really isn’t. Over the past six decades, at least one map has changed from one two-year cycle to the next a little more than 75% of the time (24 of 31 two-year congressional election cycles). That tally includes 2024, as five states changed their maps for a variety of reasons. [...] So, who won? Probably Republicans, but only modestly."
