How about the CP?
2000 & 2004 The CP achieved ballot access in 41 and 36 states respectively. Though the party was on fewer state ballots in 2004, the vote tally increased by 40% compared to the 2000 elections while other ‘alternative’ parties lost ground or barely matched their 2000 vote totals.
2008 The CP was on the ballot in 37 states. Presidential candidate Chuck Baldwin and vice-presidential candidate Darrell Castle, endorsed by former GOP presidential candidate, Congressman Ron Paul.
NUMBERS
The CP is the third largest political party in terms of voter registration. There are 367,000 registered CP voters. (This number does not take into account the many states which do not tally voter registrations by party. In addition, thousands of voters registered with other parties have chosen to vote for Constitution Party candidates at the national, state and local levels.)
One quarter of all voters nation-wide are registered as independent or as members of a ‘third party’. Over the last 10 years this has been the largest growing segment of voter registrations. Some states’ third party or independent registrations approach 1/3 of all registered voters.
Independent voters are playing a bigger role in national and local politics as disappointment with both the Republican and Democratic parties increases.

Given the political climate, I believe that right now is the best time for a third party to grab the leadership. Unfortunately it will not happen with business as usual, it will not happen unless they evolve to meet the needs of the American people.
