The National Republican Congressional Committee named 10 candidates "Young Guns" on Monday, a title designed to promote its top hopefuls for U.S. House who are running in open races or against Democratic incumbents.

The list includes several candidates who lost close 2012 contests and are back for a rematch this year — including two who lost by only about a single percentage point.

Retired Air Force Col. Martha McSally (R) is on the list. She's back for another try against Rep. Ron Barber (D-Ariz.), who narrowly defeated her in 2012 by under a point. So is former congressman Bob Dold (R-Ill.), who lost by about 3,000 votes to now-Rep. Brad Schneider (D-Ill.) and is running against him again this year.

Former Massachusetts state legislator Richrd Tisei (R) was also named a "Young Gun." Tisei is an openly gay candidate who is once again challenging Rep. John Tierney (D-Mass.).

Below is the complete list of "Young Guns" named by the NRCC:

1. McSally
2. Miami-Dade School Board member Carlos Curbelo, who is challenging Rep. Joe Garcia (D-Fla.)
3. Dold
4. State Rep. Mike Bost, who is challenging Rep. Bill Enyart (D-Ill.)
5. Tisei
6. State Sen. Torrey Westrom, who is challenging Rep. Collin Peterson (D-Minn.)
7. Mills Fleet Farm Vice President Stewart Mills, who is challenging Rep. Rick Nolan (D-Minn.)
8. Chester County Board of Commissioners Chairman Ryan Costello, who is running for the seat or retiring Rep. Jim Gerlach (R-Pa.)
9. Virginia Del. Barbara Comstock, who is running for the seat of retiring Rep. Frank Wolf (R)
10. State Sen. Evan Jenkins, who is challenging Rep. Nick Rahall (D-W.Va.)
