Environmentalists launch seven-figure ad campaign against Montana GOP Senate candidate

An environmentalist group launched a seven-figure ad blitz Thursday attacking Montana Senate Republican hopeful Tim Sheehy, a boost for vulnerable incumbent Sen. Jon Tester (D-MT).

The new 30-second ad spot, “Signs,” criticizes Sheehy’s stance on public lands. It opens with some footage of Montana’s rolling hills and snow-covered fields before zooming closely on a large, black-and-orange sign that reads, “Private Property, No Trespassing.”
