What to watch Tuesday: Redistricting scrambles Florida as Alaska pits Dan Sullivan v. Dan Sullivan

As primary season concludes, focus shifts to Florida, Wyoming, California and Alaska, where Republican-led redistricting efforts have disrupted congressional maps and sparked clashes between the Democratic establishment and progressive left. Tuesday's primaries in these states will showcase the consequences of these redistricting changes and serve as a barometer for the midterms, where Republicans currently hold a narrow edge.

In Florida, the Republican Party's nominee to succeed term-limited Gov. Ron DeSantis is Byron Donalds, a rising Republican star who would be the state's first Black governor if elected. If successful, Donalds would join a growing list of Black gubernatorial aspirants, including Michigan's John James and Minnesota's Lisa Demuth.

The Democratic side features a diverse field, from David Crowley's razor-thin primary victory in Wisconsin to Attorney General Aaron Ford in Nevada, State Rep. Jermaine Johnson in South Carolina, and Keisha Lance Bottoms, the nation's first Black woman governor candidate from Georgia. The Florida GOP winner will likely face David Jolly, a former Republican-turned-independent-turned-Democrat.

Redistricting has created complex matchups in Florida, including a contentious race between Democratic Rep. Debbie Wasserman Schultz and former Rep. Sheila Cherfilus-McCormick in a South Florida district that is nearly 80% Black. Wasserman Schultz, the only white candidate, is running against four Black opponents and has faced criticism for allegedly "stabbing us in the back."

The primary contests also reflect internal battles within the Democratic Party, with progressive and establishment candidates clashing in states like Wisconsin, Minnesota and Michigan. These battles are now playing out in more conservative territory, such as Florida, where progressive state lawmaker Angie Nixon faces retired Army Lt. Col. Alex Vindman in a special election.
