NRCC grows Patriot program by 15

The National Republican Congressional Committee (NRCC) has expanded its list of vulnerable members who it will focus its incumbent retention program on.

The NRCC added 15 members to its Patriot program Wednesday, and they join the 10 members who were originally put on the list.

The new members are Reps. Mike Rogers (Ala.), Mary Bono Mack (Calif.), Bill Posey (Fla.), Tom Rooney (Fla.), Mario Diaz-Balart (Fla.), Lynn Jenkins (Kan.), John FlemingJohn FlemingClub for Growth: Anti-Trump spending proved to be 'good call' David Duke gets debate slot in La.

Posey, Rooney, Jenkins, Fleming, Cassidy, Luetkemeyer and Lummis are all freshman. The others were targeted by Democrats in 2008, with mixed results.

There are a few curious absences from the list so far.

One is Rep. Mike Castle (R-Del.). Several of the new Patriots had opponents raise big money against them in the second quarter, and Castle did too. Take it as a sign that the party believes there's little chance he will be seeking reelection.

Another is Rep. Bill Young (R-Fla.). Young comes from a tough district and has a solid opponent, yet seemingly less vulnerable members with no opponents are still being added to the list before him. Could be a sign of retirement.
