Some of the polls show that but many of the polls show otherwise, so some (or many) pollsters are going to have egg on their face tonight.
As far as Rubio coming in second, that might not be such a bad thing for Trump, especially going into Super Tuesday where many of the states are in the South. Ted Cruz is thought to do very well in the South and if he comes in third in SC, that will certainly hurt him. But if Rubio makes a strong second, the media will fawn over him again. I sure hope Trump wins big - in the double digits if possible.
I prefer to see Marco way back in third.
South Carolina would be golden if Yeb! were to come in fifth behind caerson.
