If you're one of the nearly 1 million Pennsylvania residents who are registered as independents or in third-parties such as the Green Party or Libertarian Party, you're going to have to sit out the April 22 primary unless you switch to one of the big two parties.
Pennsylvania primaries are closed to independent and third-party voters.
So if you want to have a say in the Hillary Clinton/Barack Obama contest, you have to register as a Democrat. If you want to pick between John McCain, Mike Huckabee or Ron Paul, you have to be a registered Republican.
The deadline to register for the primary or switch your party affiliation is Monday, March 24. That's the day after Easter, so you might want to get your paperwork done before that.
Find out more about how to register and deadlines at the Voters Guide on The Mercury Web site.
