How are people to make sense out of this?

If you're trying to figure whose going to win what primaries today, and by what margin, forget it.  Obama's lead in North Carolina is--variously, depending on the poll--anywhere between 4 and 14 points.  Considering trend lines, he's either gaining support (Zogby) or losing support (ARG).  In Indiana, Clinton is either down 2 (Zogby) or up 12 (SurveyUSA), and is either losing (Zogby) or gaining (SurveyUSA)--ARG says gaining too, but Insider Advantage says not. 

Pick your favorite candidate and make your own call.  Somebody out there will back you up, and, when the vote tally is in, at least a few of them are going to be further off the money than you are, and they get a lot of money to do this, and you don't get a dime.  NC:  Obama by 8.  IN:  Clinton by 6-8.
