Right after we went into Iraq the dems went crazy about protecting Iran and Syria. Note that Byrd included Syria even though no on eis mentioning Syria right now.
These are two of the worst regimes on Earth, and the dems are hell bent on protecting them. That is why the dems are so vulnerable IF the republicans had the willingness to expose them.
The democrat party must know they are biting off their noses to spite their faces with this line of talk, and allowing Byrd to mouth off the way he does. But with faces like they got, a nose or two here and there don't make much difference.
