OK. First off, who is the "gun lobby" and do you have links to support your claim? While we're waiting, though, here's a couple articles to get you started: You can see what Breitbart has to say or, if you don't trust them, here's essentially the same story from Mother Jones. Finally, just what do you suggest the "gun lobby" do to "get behind" enforcement? Bake cupcakes to send to Eric Holder? Perhaps a better question might if we can get the US Attorney General behind enforcement, given his awkward smuggling guns to Mexican drug dealers and then covering up the investigation related to it.
