I usually urge people to pay attention to political campaigns, but sometimes candidates sink so low that all you can do is turn away. Such is the fate of John McCain, a man I used to admire. McCain is now so desperate that he has sunk to using the Manchurian Candidate strategy against Barack Obama. Swampland provides an overview of the attack and Obama's response.
And just who was the Manchurian Candidate? Wikipedia tells all.
