Here's a good question -- who's that dude?
While politicians traded barbs and talked policy, Twitter had its eye on the breakout star of the GOP forum: the guy sitting behind moderator Jake Tapper.
The man in the gray suit sitting over Tapper's shoulder seemed to make hearts flutter on social media. For the millions watching the presidential debate at home, some seemed fixated on him, calling him "eye candy" and pleading for him to get in touch.
The man's identity is still unknown.
