The Gallup organization shows the President has a commanding 13-point lead in its latest poll of likely voters conducted in the past week.  A Pew Research Group poll conducted during roughly the same period finds the race a  dead heat at 46% to 46%. 

The Gallup poll was conducted normally.  The Pew people tried something new, by conducting the poll in two phases.  Whether that accounts for the difference, I don't know, but somebody is wrong here.  Way wrong.

I wonder if CBS had the Pew results certified?
