I see your point, but the difference between ISIS and WMDs [in Saddam Hussein's Iraq] would be. . . ISIS is unquestionably real.

Real and directly caused by the US Government's actions. Just like theocratic Iran and Al Qaeda.

Did they ever figure out what Saddam did with the large stock of WMD that we know he had prior? Trucked off to Syria before the invasion? Where did it all go?

I would say there are two parties, but it's not "Democrats/Republicans", it's "Tea Party/Everybody else".

There's a small group of people making Republican politicians do crazy things (shutting down the government, blockading Obama, various social issues [gay marriage/abortion]), but by and large the Democrats and Republicans are the same.
