“When I got here in the district … what I kept hearing is, we’ve got to change the party leadership,” Stone said. “We need to end the GOP’s civil war between the establishment and the conservative base, and get everybody into the same tent.”

While anti-incumbent sentiment has played a strong role in many elections, running specifically against House Republican leaders—including Boehner, Majority Leader Eric Cantor, Majority Whip Kevin McCarthy, Conference Chair Cathy McMorris Rodgers, and the rest—is novel. Moreover, Stone is not the only one.

The Republican Trust Political Action Committee credits Stone, 58, as the first candidate in the nation to sign the organization’s pledge to vote for an all-new House GOP leadership team. But it also says candidates in Georgia, Arkansas, and North Carolina have done the same.

How this plays out in their races—let alone if they get elected—is anybody’s guess. But Stone is going to find out soon, with early voting starting Monday in Georgia’s 12th District and the primary coming May 20.
