The National Republican Congressional Committee announced today that four House candidates have moved up to the Vanguard level of the committee’s Young Guns program.

The newly upgraded candidates include attorney Tom Cotton, who is running for Arkansas’ 4th district; state Sen. Doug LaMalfa, who is running for California’s 1st district; Lewis County Judge-Executive Thomas Massie, who is running for Kentucky’s 4th district; and foot surgeon Brad Wenstrup, who is running for Ohio’s 2nd district.

All four have won their primaries and are likely to become Members of Congress in the fall. Three of the four seats are open because of House retirements. Wenstrup defeated Rep. Jean Schmidt in the Republican primary.

The Vanguard designation is intended for candidates running in Republican-leaning open seats.
