Opinion: Winners of last night's debates:

I thought Rubio and Christie had the best debate performances,  followed closely by Fiorina, Santorum.  Trump and Carson were what they are,  reasonably good performances for each man but short on substance. 

Worst performances:  Kascih had the worst performance of the night.  I am tired of Rand Paul and Bobby Jindal.  Huckabee did himself no harm,  but did not separate himself from the pack, either. 

Jeb Bush had his best debate performance but, still,  nothing memorable.
