The senator has effectively not stopped campaigning since 2015 as the political landscape has shifted – but can he grow his 2020 support?
There is an saying in US politics, perhaps truer now than ever: every senator looks in the mirror and sees a president looking back. Before Bernie Sanders ran for the White House, his rumpled appearance and shock of unruly white hair suggested that this US senator gave his reflection no more than a fleeting glance each morning.
And yet, nearly two months into his second presidential run Sanders sits atop an unsettled Democratic field. It is a remarkable transformation for a democratic socialist from Vermont, deep into his 70s, who spent most of his decades-long career in the political wilderness.
