On yesterday's show, Rush Limbaugh put forward another of his signature "theories," noting in advance that he was "picking it off the wall."

"What if Ayman al-Zawahiri and other al-Qaeda leaders gave up Osama bin Laden for the express purpose of making Obama look good?" Limbaugh asked his audience.

Why would they want to do that? Because militant Islamists, according to the syndicated talk show host, want nothing more than to see Israel gone, and having Obama re-elected would help advance that goal.

"Al Qaeda was not depending on Osama bin Laden for operational leadership," Limbaugh asserted. "His day had come and gone." Letting go of an "expendable" bin Laden would net Obama "instant political capital," and help further the militants' anti-Israel cause.

"Let me put it to you this way," Limbaugh said. "Do you think that militant Islamists will be as hopeful of getting rid of Israel with a Republican president or with a Democrat president?"

No mention by Limbaugh of the fact that Israel's own defense minister Ehud Barak earlier this year called Obama the most supportive American president ever.
