A Democratic super PAC and a major labor union are joining forces and reserving nearly $20 million in ad time for the fall in a bid to topple Republicans from power in the U.S. House.
The airtime bought by the House Majority PAC and the 2.1 million-member Service Employees International Union (SEIU) means TV commercials helping Democratic incumbents and candidates will be seen in at least 47 competitive House districts.
Democrats need 25 seats to claim majority control in the House.
Despite being outspent by Republicans and their allies in independent groups, the House Majority PAC scored victories in special elections this year in New York and Arizona. Democrats Kathy Hochul and Ron Barber were elected in those races.
