Obama and the democrats want to confiscate guns not because they care about them, but because guns are a footnote in their plan of Complete Political Control.
The plan goes like this. Since absolute control can be achieved only through military insurrection or the political process, i.e., votes, and since there are enough patriots left in the military to forestall a military takeover, the only possibility for usurping control is through some form of vote fraud.
The country is evenly split between socialists and non-socialists, and all that is required to gain complete control is a few more socialist voters. How about twenty million illegals who are grateful to be let into the country and ultimately made citizens?
