I don't think the Democrats are THAT insane to turn the Iran issue into their political gain, especially since Iran has openly said they will use their nuclear capability to destroy its own enemies. Europe well knows that Iran could very soon launch a nuclear strike as far west as London, and this could set the stage for a ugly war in the Middle East that could wipe out 50% of the world's oil supply unless Iran is stopped.
I'm not so sure about that, but I sincerely hope you're right.
