Enviro group's ad criticizes Gardner in Colo. race

WASHINGTON (AP) — Groups independent of the likely nominees in Colorado’s Senate race are running ads that question the motives of the candidates, adding millions to what outside groups are already spending on negative television spots six months before Election Day.

The latest comes from the League of Conservation Voters, which announced this week it would spend almost $1 million to criticize Rep. Cory Gardner, the expected Republican nominee, as a figure who takes policy positions in exchange for support from his political patrons. In the 30-second ad, the environmental group says Gardner is beholden to billionaire industrialists Charles and David Koch and is “too extreme for Colorado.”
