On 26 September the Senate voted 76 to 22 to pass Kyl-Lieberman, an amendment to the 2008 Defense Authorization bill that expresses the "sense of the Senate" with regard to Iran. You can find more on the amendment here. It's worth noting that Hillary Clinton voted for the amendment, which expresses concern over Iranian activities in Iraq and calls on the White House to designate the Iranian Revolutionary Guard a terrorist organization. Her chief rival for the Democratic nomination, Barack Obama, did not vote. (Sens. Biden and Dodd both voted against it.) Last week, when the Senate voted to condemn MoveOn.org's attacks on General David Petraeus, Obama was also missing. He said that that vote was an example of "empty politics." There's a Democratic debate on MSNBC tonight. How will Obama justify his absence from today's vote? Will he be asked how he would have voted on Kyl-Lieberman if he had decided to vote? And doesn't "empty politics" occur when you decide against taking a position at all?
