Is This Club For Growth Ad Targeting Boustany And Richmond An Issue Ad?

This week the Club for Growth posted a new ad criticizing Louisiana congressmen Charles Boustany and Cedric Richmond for supporting the federal export-import bank, urging viewers to call the two congressmen and “tell them to stop supporting corporate welfare.” The ad does not explicitly call for the viewer to oppose Boustany, a Republican running for the Senate, or Richmond, a Democrat who is up for re-election in the 2nd Congressional district. ... Should this ad be considered an “electioneering” ad, meant to influence the election? Or is it an issue ad?
