Updated Thursday, 2:03 p.m. | House Majority PAC, a super PAC that aids House Democrats, has recently canceled around $1 million in ad reservations in races throughout the Midwest and Northeast.  

The shifts indicate Democrats are more optimistic about winning some House races — and have given up hope on others.  

These changes were spotted by sources who track media buys and confirmed by a House Majority PAC spokesman, who declined to specify the super PAC’s reasons for moving funds to or from particular House races:  

• Arizona’s 9th District: Cut $89,000 from the Phoenix broadcast television market between Oct. 14 and Oct. 20. This cut indicates freshman Rep. Kyrsten Sinema, a Democrat, is in a stronger position to win a second term. The group still has $365,000 reserved in Phoenix.
• Connecticut’s 5th District: Cut $307,500 in the Hartford broadcast television market between Oct. 13 and Oct. 23. This cut indicates Democrats believe freshman Democratic Rep. Elizabeth Esty is also in a strong position for a second term. $309,000 remains in reservations.
• Illinois’ 13th District: Canceled an undisclosed sum in the St. Louis broadcast television market between Oct. 14 and Oct. 20. This is likely a signal Democrats have lost hope to pick up Republican Rep. Rodney Davis’ seat.
• Michigan’s 7th and 8th Districts: Canceled an undisclosed sum in the Detroit broadcast television market between Oct. 14 and Oct. 20. This telegraphs reduced confidence in picking up retiring Rep. Mike Rogers’ 7th District and Rep. Tim Walberg’s 8th District.
• New York’s 18th District: Cut spending in $102,000 on New York City cable. This is likely a sign of confidence in Democratic Rep. Sean Patrick Maloney’s re-election.
• Pennsylvania’s 6th District: Canceled an undisclosed sum on broadcast and cable between Oct. 14 and Oct. 20. This means Democrats are likely glum about capturing retiring Republican Rep. Jim Gerlach’s seat.
• Illinois’ 17th District: Cut $95,000 between Oct. 14 and Oct. 20. It is likely a sign of confidence in freshman Democratic Rep. Cheri Bustos.
