There really is only one gap for McCain: VOTERS

Despite the parsing of polls by some pundits who are all in a competition to be the smartest of the smarty pants, McCain is losing with that key constituency groups called "voters" -- in almost every single poll. In fact, McCain is constantly underperforming with actual voters in the key states that he must win in November.

If a candidate underperforms by one percent or even one vote with "voters," that candidate loses. So, I am going out on a limb here: If McCain underperforms with "voters," he loses.
