There is. But that's fine.
Then please enlighten me as to where these mythical votes are, because just saying "there is" is not a valid argument. There is no way Clinton can be up +12 when the Republican is doing average in Democratic strongholds like New York, Illinois and California (Last poll I saw for there) and have close races in the Swing states. The facts, and math in this case, do no lie.
Well, for one thing, he's incredibly weak in Texas, a state Romney won by 16 points. Also, not many polls have been conducted in the rockies and plains, but it seems likely that he'll underperform the numbers one would expect from a generic R in them. We already know that he's going to do far worse than Mitt Romney did in Utah and Idaho.
