House Majority PAC and the Service Employees International Union announced today that they are partnering in their effort to aide House Democratic candidates and will reserve $19.7 million in television advertising across 38 media markets.

The reach of that buy is “at least 47 competitive Congressional districts,” according to a press release from the Democratic-aligned House Majority PAC.

Of the nearly $20 million reserved, House Majority PAC put up $16 million and SEIU plans to spend $3.7 million.

Some of the buys are obvious as to which districts are being targeted, such as in Tucson where House Majority PAC made a heavy investment on behalf of now-Rep. Ron Barber (D). Other reservations, such as in the Phoenix and Minneapolis markets, include multiple races that are widely handicapped as competitive.
