CNN/Time poll: Oct. 25: Romney 24%, Santorum 2%
University of Iowa poll: Oct. 19: Romney 27% Santorum 3%
Marist College poll: Oct. 5: Romney 26% Santorum 3%
Alright, JJ....I'll explain it like I would in third grade so that even you will understand:
Let's take the first poll listed from CNN/Time. Romney is polling at 24%. Santorum is polling at 2%. The difference between 24 and 2 is
GREATER than 20. Therefore, Santorum is
MORE than 20 points behind Romney.
Repeat the same operation with the other polls, calculating the difference between Romney and Santorum, and you will find that in each of these examples, Santorum is trailing Romney by more than 20%.
Get it?
