Obama supporters are misrepresenting Hillary’s electability argument. The argument isn’t that Hillary has more chances in November because she has won the bigger prizes such as New York, California, and Texas; while Obama’s victories are mostly in small Republican states. The point about Hillary’s big-state wins against Obama’s small-state wins is that even though Obama has more pledged delegates, Hillary’s fewer delegates come from more significant battlegrounds (even though obviously Hillary’s camp can’t make the point as plainly as that, otherwise they are going to offend an awful lot of folk).
Hillary’s electability argument is, rather, that she has better chances in those states that will decide the November general election against McCain. And there is plenty of evidence that Hillary has better chances in four such major swing states: Ohio, Pennsylvania, Florida, and New Jersey.
There are two main ways to compare two candidates’ November chances in a particular state: how the candidates did in that state’s primary election; and what the general elections’ polls for that state say. Hillary has won the Ohio primary; she has won the New Jersey primary; she has won the Florida primary (even though it didn’t count); and she is predicted to win the Pennsylvania primary on April 22nd.
Furthermore, according to the RCP poll averages, Hillary has a better chance than Obama of beating McCain in each of those four states come November:
So Hillary’s electability argument looks pretty strong.
