State and National Polls Come Into Better Alignment

It appears that President Obama is likely to go into Election Day with a very modest lead in the average of national polls.

As of this writing, on Sunday evening, Mr. Obama led by an average of 1.3 percentage points across 12 national polls that had been published over the course of the prior 24 hours. The range was quite tight, running from a tied race in the polls issued by Rasmussen Reports, CNN and Politico, to a three-point lead in three other surveys.
