The eventual Congressional votes on trying to block the P5+1 nuclear deal with Iran continue to dominate the political landscape, with an AIPAC-led lobbying campaign pouring untold millions into advertising campaigns aimed at convincing the “undecided” Democrats to vote against the pact.

The vote is still some way off, but the left-most part of the Democrats seem overwhelmingly supportive of the president on the deal, while Republicans virtually to a man oppose it, with House Majority Leader Kevin McCarthy (R – CA) expressing confidence that there will be enough votes to block it.

As always, this means it’s coming down to the undecided votes, and while there is a strong possibility that the votes are there in the Senate to protect a presidential veto, it is by no means certain so far, with heavy lobbying continuing on a lot of the Democrats.

Voting in the House is a lot less clear, but again, the Republican majority strongly wants to block the deal, some of the Dems are on the record supporting it, and a lot of undecided remain in the middle.
