Two major Democratic super PACs are spending a combined $12 million on digital advertising focused solely on helping Democrats win 2018 House races. House Majority PAC and Priorities USA Action haven't finalized the list of races, but Priorities USA previously announced they wanted to focus on Arizona, Florida, Michigan, Nevada, Ohio, Pennsylvania and Wisconsin.

Why it matters: Democrats recognize that outside Republican groups will likely outspend them (as they have in Florida and Wisconsin), but they hope partnering together will give them advantage because they'll be working from the same plan.
