Defeated presidential candidate Sen. Bernie Sanders (I-Vt.) plans to spend the new year renewing efforts to defeat President Donald J. Trump’s policies, as well as spread his progressive message far and wide.

Sanders made his impassioned pledge in a Sunday tweet, sharing his New Year’s resolution by writing: “In 2018, we will not only intensify the struggle against Trumpism, we will increase our efforts to spread the progressive vision in every corner of the land.”

Sanders, who was defeated by twice failed presidential candidate Hillary Clinton during the 2016 Democratic presidential primaries, has a socialist vision for America that made him the hero of college students and social justice warriors. Popular promises he made, such as free college tuition and universal health care, created a loyal following that still yearns for his presidency.

As President Trump stands for conservative issues that don’t align with Sanders’ progressive agenda, Sanders has been a vocal opponent of the president and his administrative policies. Sanders has said the president should resign due to sexual misconduct allegations against him, as former Democratic Sen. Al Franken (MN) did, amid pressure from his own party following reports of sexual misconduct.

As reported Monday, Clinton donors paid $700,000 to fund women willing to accuse President Trump of sexual misconduct before the 2016 election. Accusers were solicited by celebrity lawyer Lisa Bloom, who was working with a number of Trump’s accusers at the time. The report has left many skeptical as to the validity of the claims made by Trump’s accusers, and throws water on the fire Sanders hoped to set in demanding the president resign.

Despite Sanders’ defeat by Clinton, and her defeat by Trump, Sanders supporters are still “feeling the Bern,” as he is considered a top contender for the Democratic nomination in 2020.
