Another presidential immigration speech

President Obama has again made a speech calling for immigration reform.  This is now problematic, because the political calculations behind these speeches are so transparent that they no longer have any impact--does anyone believe Obama will push hard for reform this year?  In fact, they may well have the opposite effect--the Latino voters he wants to reach are being told over and over that the Democratic Party wants their vote, yet it becomes more and more clear that speeches alone are supposed to hold those votes indefinitely.

Obama is hoping to minimize the damage that afflicts the president's party in Congress in midterm elections.  Fair enough.  But we're moving gradually toward a crying wolf situation in which people--including Republicans he claims to want to court--simply stop believing he will really take action.
