You may have noticed that sometimes participants in a political fight put significant energy into getting media to accept their definition of what "winning" is.

Now comes the American Israel Public Affairs Committee, lobbying the Democratic Senate for war with Iran. AIPAC wants the Democratic Senate to pass S. 1881, a new Iran sanctions bill, over the strong objections of the Obama administration. The administration and ten Senate Democratic committee chairs, along with the U.S. intelligence community say that passage of S. 1881 would blow up U.S. diplomacy with Iran and put the U.S. on a path to yet another disastrous Middle East war.

At this writing, S. 1881 has 54 co-sponsors: 38 Republicans and 16 Democrats (counting Menendez, the lead sponsor.)

Here's the goal that AIPAC needs to reach to claim victory, according to a Fox News report on December 27:

A total of 47 co-sponsors are now behind the legislation introduced by [New Jersey Sen. Robert] Menendez and Sen. Mark Kirk, R-Ill. Supporters are hoping to reach a 67-member, veto-proof majority [my emphasis.]

Here's the goal that AIPAC needs to reach to claim victory, according to a Reuters report on January 6:

While the bill has gained support, it remains uncertain if backers can put together the two-thirds majority in the Senate needed to override a veto by President Barack Obama [my emphasis.]

These media accounts beg the question: what exactly is the significance of a "veto-proof majority" in this situation? Who decided at which meeting that would be the threshold for AIPAC to claim victory?

It's true that the Administration has promised to veto the bill if the Senate passes it. But if the Senate never passes the bill, President Obama will never have to veto it. The bill can't be passed if it never gets Senate action. AIPAC doesn't decide what gets Senate action. Majority Leader Reid decides what gets Senate action.

So there's an unstated assumption here: if AIPAC can get 67 co-sponsors, it can bend Harry Reid to its will. But why should 67 be the magic number that AIPAC has to achieve to bend Harry Reid to its will?

That's not how things generally work over in the Republican House. In the Republican House, for a bill to see action it generally has to satisfy something called the "Hastert Rule": it has to be supported by the "majority of the majority," that is, by the majority of Republicans.

55 Senators caucus as Democrats. So the "majority of the majority" in this case would be 28 Democrats, counting Bernie Sanders and Angus King as Democrats.

It certainly would be very appropriate for Majority Leader Reid to apply the Hastert Rule in this case. Blowing up President Obama's diplomacy with Iran would be the foreign policy equivalent of repealing ObamaCare. If 67 Senators signed a bill to repeal ObamaCare, and 45 of them were Republicans, do you think Harry Reid would call that bill for a vote?

Suppose AIPAC could get all 45 Senate Republicans (7 more) to cosponsor the Menendez-Kirk bill. Then they would only need 22 Senate Democrats (6 more) to get to 67. That is, they could get to a "veto-proof majority" while only having a minority of Democrats.

Thus, if the thing that matters is a "majority of the majority," then a "veto-proof majority" is irrelevant. The number that matters is not 67 Senators, but 28 Democrats. If currently, AIPAC has 54 Senators, among whom 16 are Democrats, then the key hurdle they have to overcome to claim victory is not to recruit 13 Senators to reach 67, but to recruit 12 Democratic Senators to reach 28, a significantly higher bar, given that any Democratic Senator who signs the bill is clearly sticking a thumb in the eye of President Obama and 10 Democratic committee chairs.

Some might say: how can you be happy when 54 Senators have signed their names for blowing up diplomacy? I freely concede: it's certainly not a good thing that half the Senate, including 16 Democrats, are Diplomacy Birthers, demanding long-form birth certificates to prove that senior U.S. diplomats were not born in Tehran.

It's been 21 days since AIPAC's Blow Up Diplomacy bill was introduced. But they don't have 70 Senators on AIPAC's Blow Up Diplomacy Napkin yet - they have only 54.

This matters because people who believe that resistance is futile are less likely to resist, and the belief that resistance is futile can become a self-fulfilling prophecy. If AIPAC's war bill never gets Senate consideration, then AIPAC loses and diplomacy wins. Whatever number of Senators we need to keep off of AIPAC's war bill to keep Harry Reid from letting it be considered by the Senate, that's the number of Senators we need to keep off the bill to defeat AIPAC's push for war.
