Republicans are performing critical triage to their midterm spending strategy as they seek to hold on to their House majority in a difficult midterm year.

The House GOP’s campaign arm pulled the plug on its remaining ad buys last week for the Pittsburgh media market, where Rep. Keith Rothfus (R-Pa.) is desperately fighting to hang on to his seat in a race against Rep. Conor Lamb (D-Pa.).

It’s grim news for Rothfus, who has largely been seen as a dead man walking since redistricting left him with a Democratic-leaning district and a difficult opponent in Lamb.
