The Democratic Congressional Campaign Committee has reserved $43.5 million in television airtime in dozens of targeted House districts this fall — a signal the party is attempting to play defense and offense in a challenging midterm cycle.  

The money is split across 36 districts, including 17 pickup opportunities, according to a DCCC aide. More districts and more money could be added to the reservations as the cycle progresses, the aide said.  

The DCCC had $43.3 million in the bank at the end of April and has raised more than its Republican counterpart by large margins this cycle. The committee ended April with an $11 million cash-on-hand advantage over the National Republican Congressional Committee.  

These ad reservations give insight into which members Democrats see as vulnerable, and which seats the DCCC sees as the best possibility to take in November. They also signal to outside groups where the the party might need help on the airwaves this fall.  

However, parties can cancel or change these reservations until shortly before the advertisements air in most cases.  

Here are the districts where the DCCC has reserved airtime:  

Arkansas’ 2nd District: $625,000 from Oct. 21 to Nov. 4 on Little Rock broadcast. This is an open-seat race because GOP Rep. Tim Griffin is running for lieutenant governor.
