New coal ash ad targets Tillis (Raleigh News & Observer) -- A new barrage of TV ads criticizing state lawmakers over environmental issues will begin airing this week, this one singling out House Speaker Thom Tillis. This ad is the opening salvo from the N.C. League of Conservation Voters, and is part of what the organization says is a $1 million drive to hold polluters accountable and win greater protections against future spills like the coal ash pollution of the Dan River this year. Earlier this year, several state environmental advocacy groups and the national Natural Resources Defense Council kicked off a series of TV ads targeting specific Republican state legislators. The NRDC said more than $1 million would be spent. The League of Conservation Voters coal ash campaign, separate from the state and national coalition’s campaign, begins with an ad buy of $845,000 airing from Friday to July 24 in the Triangle, Charlotte, Triad and Asheville, the League says.
