Obama's Iran agreement
It is a good agreement and Congress needs to support the President. There are so many special interests. AIPAC is just one of the opponents. The Saudi's don't want it because they have a religious cold war with Iran that they want us to fight. Also, the ending of sanctions against Iran will bring their oil on to the market, which will press oil prices down. The Saudi's don't want that, and neither does the shale oil and fracking market. The Koch brothers don't want it.
The only forces supporting this agreement are the American and Iranian people. So we really need to support the President on this one.
