Bloomberg and the Fate of Independent Presidential Candidacies

Here, from a piece in today's Wall Street Journal, is one of those facts that's obvious but still worth repeating when talking about the Bloomberg for President storyline:

Whether he could actually win the presidency is another question. No independent has done so before, and the winner-take-all nature of the Electoral College means Mr. Bloomberg would have to win states, not just individual votes. Even with 19% of the popular vote, Mr. Perot won no electoral votes.
