There was one characteristic of President George W. Bush that his opponents never figured a way to effectively combat - his ability to focus all of his attention and power on one issue at a time. While his Democratic opponents were all trying to pull him into battles on health care, defense, immigration, stem cells, abortion, etc., he would pick just one issue and make it his administration's top priority. Every major speech, every major TV appearance, every major article produced would focus on that one issue, until either the president has his way or it became clear that the American people wee not behind him.
President Obama seems obsessed with the idea of being the Anti-Bush, not only undoing moves that the public was never comfortable with (i.e. Gitmo) but also taking opposite stances on nearly everything. One of those moves is trying to attack every issue and every constituency at the same time. Now, in the midst of an economic crisis, not only is trying to tackle military transformation, health care reform, and tax reform, but now also Immigration Reform (which incidentally is one of the few issues that President George W Bush focussed on but had to abandon without having his way).
Perhaps this is a "divide and conquer" strategy to force the opposition to thin themselves out by opposing every Obama priority. But it looks like a desperate man trying to make hay because he knows his time is short. And desperation is never attractive in a leader.
