Only in the last year has Kentucky been keeping a tally of how many voters are registered as members of minor parties. Furthermore, when Kentucky started tallying this information, it excluded the voters who had always been registered in minor parties, and only started counting people who had registered in them after the policy started. Therefore, the numbers have been very small.
Nevertheless, they have risen this year. In May 2006, the numbers were: Libertarian 187, Green 102, Constitution 28, Reform 12, Socialist Workers 0.
Now they are: Libertarian 341, Green 173, Constitution 49, Reform 25, Socialist Workers 15.
Kentucky does this tally for any party that has been on the ballot in the last twenty years and is still in existence.
