peculation over the 2020 US presidential elections has already gotten contentious. The Democratic field looks as if it’s going to be crowded, and new prospects are floated by the press seemingly every week, from Oprah Winfrey to Beto O’Rourke. With just under two years to go until election day, it’s best not to become too consumed by presidential speculation. But for those on the left who want to defeat Donald Trump and advance egalitarian political values, it’s important to start to think about who can succeed. For those of us who believe in radically transformative political change, the choice is already clear – Bernie Sanders is the only viable option.
