Democratic candidates seeking the U.S. Senate seat continued their push for support through a new ad, an endorsement in the city of Baltimore and a gathering with supporters in Florida. Rep. David Trone (D-6th) released his ninth campaign ad Saturday, the same week the congressman received an official endorsement from the National Education Association. The 60-second video entitled “Teachers” features public school educators, who only use their first names, summarized the need for more funding, counselors and other educational resources.
