The DCCC has cut ad buys Oct. 23-29 in four districts where the Democratic nominee is seen as having a comfortable lead, according to a party source with knowledge of the buys:

• Arizona’s 2nd district, where Rep. Ron Barber (D) faces Republican Martha McSally
• Florida’s new 9th district, where former Rep. Alan Grayson (D) faces Republican Todd Long
• Florida’s 26th district, where embattled Rep. David Rivera (R), reportedly under federal investigation, faces Democrat Joe Garcia
• New Mexico’s open 1st district, where Democrat Michelle Lujan Grisham faces Republican Janice Arnold-Jones

The committee has also cut ad buys Oct. 23-29 in seats that look like steep climbs in November. It’s viewed as a harrowing sign for the Democrats running in these districts:

• Florida’s 16th district, where Rep. Vern Buchanan (R) faces Democrat Keith Fitzgerald
• Iowa’s 4th district, where Rep. Steve King (R) faces Democrat Christie Vilsack (though this race is probably the most competitive for Democrats of this bunch)
• Indiana’s open 2nd district, where Democrat Brendan Mullen faces Republican Jackie Walorski
• North Carolina’s 8th district, where vulnerable Rep. Larry Kissell (D) faces Republican Richard Hudson
• North Dakota’s open at-large district, where Democrat Pam Gulleson faces Republican Kevin Cramer
• Ohio’s 7th district, where where Rep. Bob Gibbs (R) faces Democrat Joyce Healy-Abrams
• Ohio’s 10th district, where Rep. Mike Turner (R) faces Democrat Sharen Neuhardt
• Virginia’s 2nd district, where Rep. Scott Rigell (R) faces Democrat Paul Hirschbiel
• Wisconsin’s 8th district, where Rep. Reid Ribble (R) faces Democrat Jamie Wall

Democrats have moved the newly freed-up resources to the following districts, which the committee would appear to be increasingly bullish on:

• California’s 36th district, where Rep. Mary Bono Mack (R) faces Democrat Raul Ruiz
• Connecticut’s open 5th district, where Democrat Elizabeth Esty faces Republican Andrew Roraback
• Illinois’ open 12th district, where Democrat Bill Enyart faces Republican Jason Plummer
• Illinois’ open 13th district, where Democrat David Gill faces Republican Rodney Davis
• Illinois’ 17th district, where Rep. Bobby Schilling (R) faces Democrat Cheri Bustos
• Minnesota’s 8th district, where Rep. Chip Cravaack (R) face Democrat Rick Nolan
• New York’s 19th district, where Rep. Chris Gibson (R) faces Democrat Julian Schreibman
• New York’s 21st district, where Rep. Bill Owens (D) faces Republican Matt Doheny
• New York’s 24th district, where Rep. Ann Marie Buerkle (R) faces former Rep. Dan Maffei (D)
• Ohio’s 6th district, where Rep. Bill Johnson (R) faces former Rep. Charlie Wilson (D)
• Texas’ 23rd district, where Rep. Francisco “Quico” Canseco (R) faces Democrat Pete Gallego
