We are a little more than one month out from the 2014 midterm elections. There is an influx of new polling right now, and pundits are rampantly speculating about every possible path for Republicans to take back the Senate. But an underreported issue could be a sleeper hand grenade that ignites Election Night and blasts Republicans in several states: While almost nobody was looking, a group of third-party candidates have sprung up on the ballot like a bunch of poisonous mushrooms. Third-party Senate candidates in crucial states like Iowa, North Carolina, Georgia, Kentucky, Montana, Virginia and Alaska aren’t going to win, but they could very well make the difference in these elections. And each of these candidates –- most of whom are self-described Libertarians — has the potential to help the Democrats more than the Republicans.
