What's with right-wingers calling for a military coup against President Obama?

First it was Newsmax columnist John L. Perry. Now it's Rush Limbaugh essentially advocating a military coup by saying that when Obama outlines his Afghanistan policy at the United States Military Academy at West Point next week, “hopefully” they will “detain him” there.

Note: If you are calling for military officials to detain a president, you are calling for a military coup.

Newsmax got rid of Perry's column after we highlighted it and endeavored to distance itself from the column. But Limbaugh is more known for people apologizing to him than for apologizing for his outrageous remarks.
