To be sure, Obama's proposals to reform our immigration system, restrict access to high-capacity ammunition clips, and require universal background checks for gun sales, are all popular policies and all have majority support in poll after poll. Even a ban on assault weapons, which is not expected to be part of the legislative push, enjoys majority support as well. It's not wrong for the president to push hard on these two issues which will require relentless focus in order to pass bills that can be signed into law.
But Obama will have to be specific on a variety of issues next week. The narrower his focus, the narrower his window of influence will be in 2013, and the sooner he makes himself a lame duck.
