I used to be a Liberterian as well. I worked hard for the party for decades. After 911, I examined the effects of my efforts. There were some positive educational effects, but the primary effect was to elect far left politicians who would have lost to much more conservative Republicans if the Liberterian had not been on the ballot.
I am a registered Republican and Precint committeeman, and I am working hard to take this country back from the far left. In this election, it means electing Mitt Romney, regaining control of the Senate, holding the house and then holding their feet to the fire.
Libertarian votes cost us at LEAST a couple of US House Seats in 2010.
They cost us 6 Indiana house seats, as well.
In those close races, the Libertarian vote ELECTS DEMOCRATS
