Republican Senators are proposing legislation on Iran, on Israel, and on the U.N. that is really designed for the 2016 elections rather than for genuine legislative achievements.  The legislation cannot override a certain Obama veto.

They will get only enough Democratic support so that the most vulnerable Democrats are protected, but they are aiming for only 64 votes, not the 67 votes needed to override.  Thus, the Republicans will have their issues for 2016, and the vulnerable Dems are saved, but the country and the world go to hell, because it was all theatrics.
