Major state federations are set to secede as early as this weekend from the national organization, while Republican lawmakers who graduated from college long ago are weighing in amid accusations of election theft.

At issue, in part: the question of what happened to more than $100,000 donated by Michigan rap-rocker and one-time Senate candidate Kid Rock.

The fate of Kid Rock’s contribution has become one in a series of flashpoints centered on the claim that allies of the head of the College Republican National Committee (CRNC)—the national group that ties together the state College Republican federations—exploited an elections rule to prevent a challenger from taking power at a vote last weekend. With major state groups threatening to secede after the vote, Republicans face the prospect that a key source of campaign volunteers will collapse into disarray a year out from the midterms.
