Please do not drive or operate heavy machinery!
After last night I would say its definitely over.
Early on last night Trump tried to get Rubio to join him again in going after Cruz(as with the prior debate, two against one) , but Rubio had obviously decided he was gunning for Trump all night.
On Trump's favorite show, MSNBC Morning Joe his friends were pointing out how it took 11 debates before two would gang up on Trump.
That he was given a pass up till now.
