Representative Nancy Pelosi has told Prez Biden and House Democratic colleagues in recent days that she is pessimistic about his chances of beating Donald Trump. Pelosi, according to those who have talked with her, conveyed her sentiments in a recent phone call with the prez. One ally said Pelosi told Biden that she had seen polling data suggesting that he could not win, and the prez pushed back, saying he had polls showing otherwise.Pelosi challenged him on that. Though she does not hold a leadership post, Pelosi continues to wield considerable influence and is seen by many Democrats as a key to resolving Biden’s status. Pelosi, 84, has faced her own questions over the years about trying to retain power as she grew older.
