A Democratic primary for governor in Wisconsin remained neck and neck early Wednesday, leaving a national battle between progressive and moderate wings largely unsettled.

Francesca Hong, a 37-year-old democratic socialist state legislator and former chef and restaurant owner, is widely favored to win her party's nomination in the Wisconsin governor's race — setting up a high-stakes test of how a swing state electorate might react to the party's shift leftward this fall, as the 2028 Democratic presidential primary looms.

The week after Michigan voters narrowly chose the more progressive candidate in a Senate primary, voters in Minnesota will face a similar choice in their state's Senate primary. A southwestern Wisconsin congressional primary features a similar ideological split. And in Connecticut, the Democratic divide is less over ideology than the question of whether the party needs generational change.

Republicans, meanwhile, will be closely watching South Carolina, where a special Senate primary is the latest test of whether GOP voters remain in lockstep with President Donald Trump.
