WASHINGTON (Reuters) - Bernie Sanders is back for another White House run, but this one promises to be far different than the improbable 2016 presidential campaign that made the Vermont senator a political force.
In the 2020 race, Sanders, who announced his latest bid on Tuesday, will have to fight to stand out in a crowded field of progressives touting issues he brought into the Democratic Party mainstream four years ago. At 77, he also will face questions about his age and relevance in a party increasingly embracing more diverse and fresh voices.
