The speculation now is that President Obama will push his executive amnesty beyond the November elections, which would have the advantage of avoiding any downside in red states before the mid-terms. Why risk it now when he will really have nothing to lose after November? The down-side would be the disappointment of immigrant advocates after all this build-up and perhaps the lost political opportunity of potential Republican overreach — say, an immediate move to impeachment — but that doesn’t seem likely. All of this, of course, brings home just how arbitrary and political the president’s unilateral executive law-making is.
