British politics is a heart attack
Well, here's a bit of history to remind you of how it evolved that there seemed to be absolutely no one around to challenge the position of Tony Blair or any other New Labour politician, no matter how they might have been despised by most normal Labour supporters. John Smith, the Labour leader at the time, had to die of a sudden heart attack at the age of 56 for Blair to become the new party leader. Everyone was so happy to finally get rid of the Tories that no one seemed to scrutinize Blair enough to see that they wouldn't be getting rid of the Tories at all, just enthusiastically electing a wolf in sheep's clothing who had gone to Australia to kneel at Rupert Murdoch's feet and kiss his ring and then run around saying things like, "We're all Thatcherites now!" He won handily and made up some obvious lunacy about how Saddam could hit us with a nuclear bomb in 45 minutes or by next Christmas, apparently by magic since Saddam had never tested a nuclear device and had no delivery systems. Everyone was upset about the invasion of Iraq, but there was a problem. The only Labour politician who seemed to be in any position to challenge Blair's leadership was Robin Cook, a vocal opponent of the invasion and never an enthusiastic New Labour supporter. Cook, at 59, had a heart attack and fell and died while on holiday.
