The left absolutely hated George W. Bush. Their contempt for him was so profound and palpable that it was even given a name by psychiatrist Charles Krauthammer: Bush Derangement Syndrome. Now, most of the millions of leftists who despised the ex-president absolutely wanted him to fail; in fact, while they're loath to admit it, they felt this way even when his success was synonymous with our nation's (this even included the failure of the Iraq war). And "felt" is the operative word; they were governed by emotion and hated the man with a burning passion.
But Bush is out of office and back home in Texas. This leaves a huge void; Leftists simply cannot exist without somebody to hate. Isn't it interesting how they've evolved from flower children (think Jefferson Airplane: "Somebody To Love") into something so toxic?
Suddenly, along comes a guy who very honestly notes that many of the new President's policies and perspectives are wrong for America. They might fly in Kenya, but the guy's President of the USA. Given these facts, it's logical to hope that he fails.
Bam! A hate-magnet for the Left has emerged. Rush Limbaugh has in recent days been referred to as a corpulent drug addict who is the real leader of the GOP, and even Bam himself has been uncharacteristically uncool where Limbaugh is concerned.
This looks like a Leftist hate-pattern with some real staying power.
