Sen. Bernie Sanders (I-Vt.) is making a second run for the Democratic presidential nomination, he told Vermont Public Radio on Tuesday morning. "We began the political revolution in the 2016 campaign, and now it's time to move that revolution forward," he said. Sanders followed that up with an emailed announcement to supporters. He isn't the underdog he was in 2016, when he challenged Hillary Clinton, and this year's primary is also much more crowded and more in line with Sanders' ideology. He listed the popularity of his ideas as one reason he's running again, as well as the need to defeat President Trump, and he said all candidates should be judged on their ideas and abilities, not age, gender, or skin color.
