Opponents of President Barack Obama’s nuclear pact with Iran tried turning up the heat this week on undecided Senate Democrat Jon Tester with a TV ad saying politician like him would have “blood on their hands” if they supported the deal.
The House and Senate are slated to vote next month on a resolution of disapproval.
The ad by Citizens for a Nuclear Free Iran is tougher than an earlier one it ran. But the ad doesn’t ask viewers to take any action, like calling their senator or congressman. And it doesn’t name names. Instead, it displays the group’s website address, where those inclined to visit will find more information and get automated assistance in calling their lawmakers.
“If part of what you’re trying to do is influence members of Congress to vote against the deal — it’s not the members of Congress who are going to see this, you’re targeting it to their constituents — so I don’t understand why there isn’t a call to action at the end of the ad. You know, ‘Call Congress, call your congressman’ to generate heat that way,” said Rodell Mollineau of Rokk Solutions.
The ad aimed at Tester — whose staff has yet to see it aired on Montana’s airwaves — was produced by a group called Vets Against the Deal and features an Iraq War veteran who was badly wounded by a blast from an Iranian-made bomb.
“Every politician who is involved in this will be held accountable. They will have blood on their hands,” says retired Staff Sgt. Robert Bartlett, whose facial scars are evident.
The ad won lots of attention from conservative websites and Bartlett appeared on Fox News.
The AIPAC-allied group is also running ads in the Philadelphia media market, aimed at Sens. Bob Casey, D-Pa., Coons and Cory Booker, D-N.J.
“Sen. Coons is paying closer attention to the calls, emails and letters the office is receiving from constituents regarding the Iran deal,” said his spokesman, Sean Coit.
Another group, United Against Nuclear Iran, is also running ads. It’s headed by former Sen. Joe Lieberman, I-Conn., though he was enlisted after the group’s president, Gary Samore, stepped down because he supports the accord. Also in support is liberal advocacy group J Street, which is spending $5 million to back the agreement.
Sen. Chuck Schumer of New York has publicly come out against the deal.
