IT TAKES a Sarah Palin to leap to the defence of Donald Trump on the ground that the media is exaggerating his interest in where Barack Obama was born. She thinks it is unfair of journalists to imply that his birther nonsense is "all he's got". I submit that apart from some reality-TV celebrity, it is just about all he's got. What else explains his suddenly rising popularity among Republicans? His support for a Canadian-style health-care system? Besides, shouldn't believing in a mad conspiracy theory disqualify him from serious consideration as a presidential candidate? There's some more on the Trump foolery in my print column this week.
