Tonight's Republican Debate is sure to be entertaining.

Donald Trump will literally be center stage at Quicken Loans Arena in Cleveland. The rest of the GOP field will flank The Donald.

He claims that he will only attack if he is attacked.

For the struggling field, the temptation to try and land a zinger against Trump may be too hard to resist.

Ultimately, this debate will be 'won' by whoever produces the best soundbites and YouTube moments that can be repeated and shared.

However, the only thing social media will like more than a big win is a big gaffe.

Any moment of a candidate stumbling is sure to go viral, and not in a good way.
