At 83 years old, Sanders is not running for president again. But the stooped and silver-haired democratic socialist has emerged as a leader of the resistance to Donald Trump's second presidency. In tearing into Trump's seizure of power and warning about the consequences of firing tens of thousands of government workers, Sanders is bucking the wishes of those who want Democrats to focus on the price of eggs or "roll over and play dead." For now, at least, Sanders stands alone as the only elected progressive willing to mount a national campaign to harness the fear and anger of the sprawling anti-Trump movement.
