A well-placed Senate Democratic aide emails this tip: "Expect many Senate Dems to push for the Senate to not do Iran sanctions without Russian sanctions."
What this means: Democratic leaders will exploit the ties between Iran and Russia — and the administration's weak position with regard to anything concerning Russia — to demand that no new sanctions are imposed on Iran without additional sanctions to Russia.
Our thought bubble: Democrats who support the Iran nuke deal, like former Secretary of State John Kerry, are worried about a bill that passed through the Senate Foreign Relations Committee last week. The bill imposes new sanctions on Iran over its ballistic missile tests and other destabilizing behavior. These additional sanctions don't relate to the nuclear deal, but some Democrats are anxious that imposing these sanctions could unravel the Iran deal.
