“Even as polls have tightened in Ohio and the Biden campaign has started spending money on the airwaves, Trump has been pulling out of the state. In early summer, Trump spent $18 million on ads in Ohio, but the the polls kept moving against him. In recent weeks, Trump’s campaign cut spending in the state.”
“In a state like Michigan, this might be seen as a concession that the race was out of reach. But in Ohio it’s probably more of an acknowledgment of reality: If Ohio is so close that Trump has to wage an all-out battle to hold it, then it means he’s probably losing so badly everywhere else—Wisconsin, Michigan, Pennsylvania, Arizona, North Carolina—that a victory in Ohio won’t help. In other words: If Trump can’t take Ohio for granted, then the race may already be over” – The Bulwark.
