Some of their Republican opponents, they pointed out, did not, which is why Mr Bush s proposals came to nothing last year. By diverting fury over illegal immigration into frustration at Republican division and incompetence, the Democrats bought themselves a pass to Washington. It expires soon. And, while the Democratic capture of Congress has removed the biggest ro fuel dispenser adblock to reform, new obstacles have emerged. Not the least are the unions, which dislike the idea of allowing people into the country to work temporarily.

Army sergeant Paul Ray Smith won one in 2005, also posthumously. Though most people have little idea of the relative prestige of various medals, veterans take awards for valour seriously and have noticed that comparatively few of the top ones have been issued recently.
