Senate resolutions are fairly common. There are 3 types. This one would be a Simple Resolution verses a Joint or Concurrent Resolution.

Look, it's not binding, has no weight and has no force of law whatsoever. The weight in the matter is in the hijacking by the far left of the Democrat party. Democrat leadership is aligned with the STATED political goals of OBL and Democrat constituents are very much NOT.
The base of this far left group has bought into things from misrepresentations to outright LIES. 'Who cares if it's true-I BELIEVE IT' is what the far left survives on. Some examples:
-Bush STOLE the 2000 election and/or the Supreme Court SELECTED him to be President. This is flat untrue but the emotions of the day were played on and the slogan was a hit so it was repeated and repeated till it was excepted as fact by those that didn't like the outcome and were done looking at the facts that unfolded.
-Bush lied about WMDs. Misleading. Bush, Clinton (both of them), Biden, Britain, France, Germany, the UN were WRONG. If you believe something is true and say it are you LYING or MISTAKEN.

-America's involvement in Iraq or ANYWHERE is why Islamic Fascism does what it does. A LIE. They attack Russia, Spain, Malaysia, the Philippines, Thailand, Kazakhstan, and ANYWHERE that they have a grievance because they lack the ability to address their grievances in a civilized way. Hell they BURNED France for weeks.
-Bush knew about/caused 9/11. SHAMELESS LIE. Without all the impossibilities of this illustrated let's ask this, how can he cause a complex and vast conspiracy such as that would have to be AND maintaining secrecy BUT NOT able to plant some WMDs in Iraq for someone to find.
I think Dan Rather summed it up very well when he said "The evidence in these allegations may be fabricated but I still believe it's true." After it was discovered that the Bush service record documents were forged from inside CBS during the 2004 election.
There are SOOOOO many more but the whole point is this ad was the revealing of the nature of the far left. They are now 'outed' and the resolution vote tally effectively 'outed' their inside operatives.
Create a monster and it will eventually turn on you, every time. In this case the monster didn't intentionally turn on them, it was realized as a pariah and it's associates' anonymity was blown.
Again Thank You MoveOn.
