The 11th Republican debate from Detroit, Michigan on Thursday, March 3, 2016. Which is where Rubio was really flailing and getting into an insult-fest with Donald Trump.
This was the worst debate since... well... the (10th) Fort Worth, Texas CNN debate on February 25th:
In both you see Ted Cruz and particularly Marco Rubio stepping up their personal attacks on Trump, in a desperate bid to get more media coverage that Trump is dominating with such remarks, in a final last-ditch ploy to save their candidacies.
Particularly before the Fort Worth debate, I wonder if Rubio and Cruz spoke prior and coordinated their attack on Trump.
