On Oct. 5, the liberal pro-Israel group J Street began airing the first television ads attacking Republicans who voted against the nuclear deal with Iran.
The $500,000 ad buy targets two incumbent senators in the crucial swing states of Pennsylvania and Wisconsin, Pat Toomey and Ron Johnson. Their Democratic opponents, Katie McGinty and Russ Feingold, respectively, have both come out in support of the agreement even though they were not in Congress to vote for it.
