I’ve asked this question one way, and now I’ll ask it another way – in the latest Zogby, we’re told Obama leads by “15 points among independents.” But he leads that poll by 5 percent overall.

Now, unless there was a sudden drop in the number of Democrats who back him, or a sudden mass extinction of the Obamacans, wouldn’t you figure a 15 percent lead among independents would mean a bigger lead? Particularly if Democrats are supposed to be a bigger share of the electorate than Republicans this year?
