Voting Day

With voters lining up at the polls in Indiana and North Carolina, here's a really nifty delegate tracking toy from NYTimes. Given your guess on how well the candidates do over the last few races, it tells you how many superdelegates each needs to sway in order to win. For Clinton, the math is pretty ugly: she needs a rout. Obama can win a war of attrition at this point, though he'd really like to end the primary campaign with a mandate instead of a margin.
