WASHINGTON — Representative Eric Cantor of Virginia, the No. 2 House Republican, will resign his leadership position, effective July 31, according to leadership aides. The move follows a stunning defeat in a primary election Tuesday in which voters rejected him in favor of a more conservative candidate.
The move culminated a precipitous fall for Mr. Cantor, who was thought to be a likely successor to Speaker John A. Boehner.
By stepping down as majority leader, an aide to Mr. Cantor said, he hoped to limit a festering struggle within the House Republican caucus over who would assume his post.
