What the author of this article has failed to mention is that, since the presidential election is not a direct election, but rather a (with only one exception: Nebraska) winner-take-all, state-by-state election, voters in uncontested Democratic strongholds such as my home state (California) will not hurt Romney's (already dismal) chances by awarding their vote to the Libertarian Party.
Of course, voters with 3rd-party preferences in so-called "battleground" states would do well to reconsider "wasting" their votes. Conservative voters in such states would indeed be favoring Obummer by strictly "voting their conscience."

Have, in the meantime, determined that Maine likewise can split its electoral college votes.
