Molly O’Leary, Chief of the Pennsylvania Voter Registration Division, has ruled that the state will tally voters who are registered in the Constitution, Green and Libertarian Parties. This is the first time Pennsylvania has ever performed this service for a group that does not meet the definition of "political party".
Those three parties lost their "party" status in November 2006, when they each failed to poll a number of votes equal to 2% of the highest vote-getter’s vote total. Those three parties were kept off the 2006 ballot for statewide office, so they obviously couldn’t meet the vote test.
The Pennsylvania policy is also followed by Alaska, California, Colorado, Delaware, Iowa, Kentucky, Louisiana, Massachusetts, New Jersey, New Mexico, New York, Oklahoma (in very limited circumstances), South Dakota, and Utah. All political parties benefit from having access to such lists.
