Trump played a central role in the race’s only debate, with Cardin calling for a strong Senate to stand up to the president. Campbell, meanwhile, did not seek to distance himself from the president, as Republican Gov. Larry Hogan has done. Instead, he strongly endorsed some of Trump’s signature policies, including building a wall on the Mexican border and reducing the role of the U.S. Department of Education in local affairs. Simon said he did not vote for Trump but agreed with some of his actions, including moving the U.S. Embassy in Israel from Tel Aviv to Jerusalem.
