It's been a rough couple of days for the O-godosphere (Obama's online cheerleaders). First he makes a political calculation to abandon public financing so that he can use his own online ATM (otherwise known as "small donors"). Then he capitulates on a reworked FISA bill, which was passed by the House of Representatives on Friday.
Obama is at least old enough and smart enough to know that his decisions must, of necessity, be political; that they are frequently the best-available and best-intended compromises; and that this is how the world works (more often than not). His young supporters do not know this.
