At the risk of being an "Eeyore" and called a troll I think a lot of the tooth mashing over the Dem leaning polling samples is off. I hope I'm wrong but I think the outrage is mostly a result of a lack of technical understanding. It's always dangerous when amateur analysts start tearing into poll internals. This year it seems like laymen want to start weighting polls at their own whim. There's a reason pollsters historicLly do not weight by party ID.
That doesn't mean that Dems will outperform or even match 2008 turnout. They won't. But the Dem party ID advantage in many polls is the result of Soft GOP voters being more likely to ID as indies this year. You'll notice that in most polls where Romney leads big amongst indies the party ID gap is the most favorable for Dems. When the indie vote is closer the party ID is tighter. Again, when GOP leaning indies call themselves Republicans they tighten party ID. When they call thenselves indies Romney wins indies bi but suffers in party ID.
I don't know why Republicans are less likely to ID as such this year. Bu it doesn't change he sxientific math. Pollsters know with fair certainty what the sex/age/racial composition of the electorate will be. So when you weight that way and get a scientifically representative sample the top line number will be right. At least with the 95% lvl of confidence.
This isn't to say a massive GOP turnout couldn't fly under theradar or that pollsters don't struggle with urnout models and intensity. This is gonna be a close election but the polls point to a soight Obama edge. Let's not fool ourselves. We need an upset.
Oops! Hat tips to Old Sarge and Arrowhead1952 as well!
Sorry, guys!
” im Cramer’s seriously suggesting Obama will pick up Georgia, Texas, Montana, South Dakota, Missouri, Indiana, and North Carolina.”
I wonder how many mom & pop investors went under following Cramer?
