Rick Perry’s stumble in last night’s CNBC debate -- in which he took 53 seconds to come up with the name of a third government agency before giving up -- was a top rising search last night and is this morning’s most-viewed YouTube video in the United States. Footage of the "oops" moment was viewed over half a million times in the twelve hours following the debate, and that number is still climbing.

Where is it popular? Where it matters most. Today, the Perry gaffe is the most-viewed video in both Des Moines and Cedar Rapids, two Iowa cities which are incredibly important to GOP hopefuls with the Iowa Caucus just weeks away.

Nationwide, the footage also sits atop this morning’s Trending Video list and is the #2 most-shared in the United States, placing well ahead of Ellen and Lebron.
