CNN poll in Ohio with Johnson included had him at 5%
The Libertarian Party peaked over three decades ago in 1980 with 1.1% of the national vote. So, probably somewhere in the 0.4%-0.8% range.
Probably <1%. Any uptick from more liberty leaning people will probably be counterbalanced by people writing in Ron Paul and others like myself who won't vote for GJ because he isn't a pure libertarian.
Shoot, my Mom, Stepdad, girlfriend and me are all voting GJ. So I sure hope he gets 5% Im guessing 2-3% though.
Regrettably he isn't going to do well. I'm going guess 1 percent of slightly less. I think he does better than Bob Barr.
