"place among the top five candidates in an average of national and South Carolina Republican presidential polls"
I don't understand what this means. Do they mean top five in either the national average OR the South Carolina average, or do they actually mean that they are going to average the national AND South Carolina polls together? If it is the latter, then that is absurd.
Edit: I suppose they could also mean top five in both averages individually, rather than either/or.
Sounds like they are averaging them together. It's a bit weird, especially if there happen to be more national than South Carolina polls. Maybe they average the averages?
