EXPLAINER: Why AP hasn’t called Pennsylvania


By BRIAN SLODYSKO, the Associated Press

The Associated Press has not declared a winner in the battleground state of Pennsylvania, because there were roughly 1 million votes left to be counted Wednesday afternoon in the contest between President Donald Trump and Democrat Joe Biden. Trump, who held a 675,000-vote lead early Wednesday, prematurely declared victory in the state. By Wednesday afternoon, his lead had slipped to 326,000. And the race is destined to get tighter.  The vast majority of the votes left to be counted there were cast by mail  — and that is a form of voting that Biden has carried by a large margin. That’s probably because Trump has spent months claiming without proof that voting by mail would lead to widespread voter fraud.
