THE FRONT page of the Aug. 10 Boston Globe provided an interesting contrast between our two senators. Senator Kerry had been appointed to the 12-member congressional committee charged with cutting $1 trillion from the federal deficit (“Kerry chosen for debt deal’s key panel’’). Senator Brown, on the other hand, was pictured playing a game of Uno with children in Dorchester (“For Brown, politics is still local’’). It appears that each of them has found a suitable place on the public stage. The US Senate may be the most exclusive club in the country, but it still matches skill sets to public service.
