It’s not just earlier primaries that could doom underfunded presidential candidates hoping for a push from a breakout performance in Iowa or New Hampshire. (Mike Huckabee, to name one underfunded candidate, has talked often of concentrating on the Jan. 29 New Hampshire primary.) Problem is, the Wall Street Journal notes, isn’t just earlier primaries in many states, but early voting laws that mean millions and millions of voters in vote-rich states will have already voted by the time New Hampshire rolls around.
