Here’s a little secret — a recent McClatchy poll blows the lid off a little known fact.
When you poll voters — and include people whose only phone is a cell phone — Democrats lead by 6 points on the generic ballot. This follows a Newsweek poll last week that also shows Democrats up 6 points when you include the cell phone only population.
Here’s another little secret: McClatchy’s latest polls look even worse for Democrats than the others. Via RealClearPolitics:
