Most of the Republican debates have been Trump vs. everyone else. Even though Ted Cruz was the winner in Iowa, tonight was very much everyone else vs. Marco Rubio. The biggest fight of the night was actually Christie at Rubio.
The Democrats had Hillary vs. Bernie in a state where Bernie has a good chance of winning. They are now facing off directly, with no O’Malley buzzing around. Hillary got just under 50% in Iowa. Can she break 50% in South Carolina?
I suspect that regardless of what happens in New Hampshire, Cruz has a good chance of winning SC. Even though Carson is more evangelical, the religious right in that state likes to win and Cruz is their non-Trump choice.
