In short, the voting public the PPP poll assumes should not be that close to what actually manifests on Nov. 4, 2014, and the most optimistic rendering of her chances continues to be they are uncertain. The most pessimistic would be she is in trouble with these numbers which is why she continues to be listed from many quarters as one of the most endangered, if not the most endangered, Senate Democrat of the cycle.
POSTSCRIPT: A reader reminds that the days of the polling occured right at the beginning of Carnival weeked and extended all the way through Mardi Gras. Granted, north of U.S. 90 there's precious little Carnival activity, but considering that Republicans more than Democrats (and to a lesser extent, conservatives more than liberals, even as there is dispute as to the reasons why the partisan relationship has been witnessed for decades) feel happiness in their lives, you might expect they'd be the ones more likely to hit a parade or party -- or show up to work instead of taking the day off. Maybe Democrats disproportionately stayed home, preferring to scan websites in order to leave vitriolic posts or spleen-venting comments on various VRWC theories, blaming Bush and the Koch brothers for every imagined evil in the world, etc.?
