The botched health care site, Malaysian Airlines and midterm elections were all fair game Saturday at the 100th annual White House Correspondents' Association dinner. Celebrities and politicians laughed and cheered President Obama and host Joel McHale as they poked fun at everything from the beleaguered launch of the government healthcare site to foreign leaders. "That could have gone better," the president said of the health insurance site launch. "In 2008 my slogan was 'yes we can.' In 2013 it was control, alt, delete.' "Mr. McHale pointed out it was hard to quantify how terrible a launch the site really had because it serves as the basis for analogies.
