Rasmussen reports that
Libertarian voters make up 4% of the nation’s likely voters and they favor Barack Obama over John McCain by a 53% to 38% margin. Three percent (3%) would vote for some other candidate and 5% are not sure. These results, from an analysis of 15,000 Likely Voter interviews conducted by Rasmussen Reports, challenges the conventional wisdom which assumes that strong support for a Libertarian candidate would hurt John McCain.
In June, Rasmussen Reports asked 15,000 Likely Voters if they were fiscally conservative, moderate, or liberal and if they were socially conservative, moderate, or liberal. This created a total of 16 possible combinations (not sure was a fourth option for both questions). However, 87% of voters fit into one of seven combinations. Libertarians, defined as fiscally conservative and socially liberal, are the smallest of these seven combinations.
