Yet again, congressional Republicans have devoted time and energy to hitting the Obama administration over the incident in Benghazi, Libya, where a diplomat and several other State Department employees were killed in an assault by a heavily-armed group. The administration insists that this was a tragic accident, and an investigation has cleared officials of wrongdoing or serious mistakes. But Republicans continue to believe that this was mishandled, to the extent that administration officials are covering up key information.

There are few things that irritate Republicans more than the fact that Barack Obama went through an entire term with nothing but minor scandals to tie him down. No Watergate, no Iran-Contra, no Lewinsky, not even a little Valerie Plame. It wasn't that the GOP didn't try to create one, though. There was "Fast and Furious," in which the administration supposedly let Mexican drug gangs get all kinds of weapons from the U.S. on purpose, so that when it was revealed it could be used as an excuse to take away everybody's guns. Despite the Republicans' best efforts, the conspiracy theory didn't pan out. There was Solyndra, in which the administration supposedly knowingly squandered taxpayer money on a bunch of their cronies using a technology destined to fail.
