I would bet yes, gun confiscation is a key element of the left; and, it's a chance to tar the Tea Party for something in which they had no part. His minders will, I suspect, put "common sense" gun control legislation in the speech ("common sense" being a liar's gimmick to fool folks into thinking that they would agree with the rules, that the rules would be unobstrusive, and that we somehow needed them all along.)
Probably something similar to ... " the tragic events in Tuscon remind us that there is still a need for common sense gun regulations to keep our population safe from those who can't control their hate and who would settle political discussions with violence."
.
Those of us who have been around for a while know that "common sense gun regulations" means total prohibition on gun ownership by anyone except government functionaries.
The anti-gunners never rest. They cannot be reasoned with. They cannot be appeased (every new restriction is a "good first step.") They view the meaning of "compromise" as meaning "not getting complete probition right away." They cannot be bought off. They have no mercy on those who would protect themselves and their families from violence. They cannot be educated for they have already made up their minds. This can only end one way.
